A doctor is measuring the mean systolic blood pressure of female students at a large college. Systolic blood pressure is known to have a skewed distribution. The doctor collects systolic blood pressure measurements from random sample of 28 female students. The resulting 90% confidence interval is (100. 4, 159. 6). Units of systolic blood pressure are mmhg. Which one of the following conclusions is valid?
Using the Central Limit Theorem, it is found that the valid conclusion is given as follows:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have a skewed variable with a sample size less than 30, hence the Central Limit Theorem cannot be applied and the correct conclusion is:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.

How career and study choices are influenced by availability of finances/affordability
There are several elements that might impact a person's profession decision. This decision-making process begins when high school graduates decide on the degree they want to pursue while keeping their budget in mind. A college degree is a valuable commodity that many young folks want to get, but it is also growing increasingly expensive. Many students choose a more cheap and practical degree over what they actually want to study because of economic considerations. In truth, college affordability is a catastrophe that the United States is currently confronting. According to the College Board, students at public universities spend more than $20,000 on tuition and room and board alone during the course of a four-year degree. As a result of the crisis, many students are obliged to pursue less costly occupations, which means they must take less expensive degree programs. The cost of receiving a higher education might impact an individual's study choices and, as a result, his or her future employment choices.

A 20 kg box rests on a table. What force does the earth exert on the box?
Answer:
The normal force acting on the body is equal to its weight, hence;
N = W = 196N
The normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N
The formula for calculating the weight of an object is expressed as:
W = mg
m is the mass of the object
g is the acceleration due to gravity.
Given the following parameters
Mass of the box = 20.0kg
a) The weight of the box = 20 * 9.8
Weight of the box = 196N
Hence the weight of the box is 196N
Note that the normal force acting on the body is equal to its weight, hence;
N = W = 196N
b) if a 10.0-kg box is placed on top of the 20.0-kg box, the total mass will be;
M = 10 + 20 = 30kg
total weight = 30 * 9.8
Total weight = 294N
Since the normal force is equal to the weight, hence W = N = 294N
Weight of the 10kg box = 10 * 9.8 = 98N
Since the 10kg box is on top of the 20kg box, hence the normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N

Find the mass of alcl3 that is produced when 10. 0 grams of al2o3 react with 10. 0 g of hcl according to the following equation. Al2o3(s) + 6hcl(aq) → 2alcl3(aq) + 3h2o(aq)
The balanced reaction
Al₂O₃ (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂O (aq)
says that 1 mol Al₂O₃ reacts with 6 mol HCl to produce 2 mol AlCl₃.
We start with
• (10.0 g Al₂O₃) (1/101.96 mol/g) ≈ 0.0981 mol Al₂O₃
• (10.0 g HCl) (1/36.46 mol/g) ≈ 0.274 mol HCl
We can use up to
(0.274 mol HCl) (1 mol Al₂O₃ / 6 mol HCl) ≈ 0.0457 mol Al₂O₃
and consume all the HCl in the process (while also leaving an excess of about 0.0524 mol Al₂O₃) to produce approximately
2 (0.0457 mol Al₂O₃) (2 mol AlCl₃ / 1 mol Al₂O₃) ≈ 0.183 mol AlCl₃
This has a mass of about
(0.183 mol AlCl₃) (133.3 g/mol) ≈ 24.4 g AlCl₃

The electrical conductivity of an aqueous solution depends on the concentration
The concentration, mobility, and valence state of the ionized species in a solution, as well as the temperature at which the measurement is done, all have a role. The conductivity of water increases with the concentration of ions in it.
A mixture of sodium hydroxide, naoh(s) and benzoic acid, hc7h5o2(s), consists of a total of 0. 50 moles. This mixture is dissolved in 1. 0 l of water and the ph of the resulting solution is determined to be 12. 52. Find the mole fraction of benzoic acid in the initial mixture
With a resulting solution of 12.52 and 1 m.l of water, the mole fraction of Benzoic acid that is in this mixture is 0.4669
How to solve for the mole fraction of Benzoic acidpH = 12.52
pOH = 14 - 12.52
= 1.48
OH⁻ = [tex]10^-^1^.^4^8[/tex]
= 0.0331
The concentration of excess ionsThe total number of excess OH⁻ that is required to make salt
= 0.5 - 0.0331
= 0.4669
H+ = 0.4669/2
= 0.2334
The mole fraction of Benzoic acid that would be here would be gotten by:
0.2334/0.5 = 0.4669
We conclude that the mole of Benzoic acid would be 0.4669 moles.

You are looking at comparable houses with the same asking prices in neighboring towns. The mill rate in the first town is 20 mills. The mill rate in the second town is 37 mills. Both houses are assessed at $175,000. Mill rate is the tax rate that is applied to the assessed value of a real estate property by a municipality. Your tax is calculated by multiplying the mill rate by the assessed value of a property and dividing by 1,000. What is the dollar difference in annual property taxes based on mill rate between the two towns?
The dollar difference in annual property taxes based on mill rate between the two towns is $2,975.
Dollar difference in annual property taxesFirst step is to calculate for first town
First town=Mill rate÷1,000×Property assessed value
First town=20 mills÷1000×$175,000
First town=$3,500
Second step is to calculate for second town
Second town=Mill rate÷1,000×Property assessed value
Second town=37mills÷1000×$175,000
Second town=$6,475
Third step is to calulate the difference
Difference=$6,475-$3,500

Do you think evil exists? Is there an ultimate cause of evil? If there is an ultimate cause of the good (for example, God) and an ultimate cause of evil (for example, the Devil), which ultimate cause is greater? How do you know? If God exists and God is good, then why does God allow evil in the world? Can God design a world without suffering? If God is dead or does not exist, does this mean that evil will take over the world? Can good exist without God? Are humans free to do evil acts if they have free will? If yes, then is giving humans free will in fact an evil act? Can a person be evil while going good deeds?
Answer:
Evil people don't exist, but evil actions do.
Explanation:
No one can be born completely evil, but they could have done evil things. There isn't one cause of evil, rather, there are many and they vary. An example of one could be massacre ten people because those people killed their child, or friend, or relative of some sort. While it isn't right, there is usually motives. Someone who has hunger for human flesh will kill humans to eat them. It also isn't right, but the hunger is the motive, not the main drive of the person. I don't think God and the Devil exist, but if they did, God could not create a world without suffering. It is impossible to watch everything at once and if God helped us too much, we'd be helpless to defend ourselves and we could not function or advance without God's help. Good can exist without God, because there are always good people out there. Humans are free to do evil acts if they have free will, but that doesn't mean everyone would do evil acts. Giving humans free will is not an evil act, it's like giving lifeless puppets life and watching them. Refusing humans free will is also an evil act, it is basically like slavery. Yes, a person could be evil while doing good deeds because like I said, no one is completely evil.
