An experiment was conducted to determine whether the price of a golf club affected the distance a golfer could hit a golf ball. A sample of 60 golfers were randomly assigned to one of two groups, c or e. The 30 golfers in group c were given a club and told the price of the club was cheap; the 30 golfers in group e were given the same club and told the price of the club was expensive. In reality, there was no difference in price. The golfers used their assigned clubs to hit a golf ball as far as they could. The distance, in yards, that each golfer hit the golf ball was recorded, and the mean distance calculated for each group. A two-sample t-test for a difference in means will be conducted
The true statements about the data from the t-test will be:
The data was collected using random assignment, the golfers were assigned randomly to the two groups.The data was also collected using random selection.The distribution of the difference in the sample means will be normally distributed as well according to the central limit theorem.What is a t-test?
A t-test simply means a type of inferential statistic that is used to determine if there is a significant difference between the means of two groups,

Lin is the regional manager for a chain of stores. She wants to determine which store should receive a higher volume of team wristbands. The box plots represent the number of team wristbands sold daily at two of Lin’s stores. Which store has a greater variety of numbers of wristbands sold? How do you know?
The store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.
How do we Determine Variability in a Box Plot?Variability of a data distribution that is represented by a box plot can be determined by the interquartile range (IQR) = Upper Quartile (Q3) - Lower Quartile (Q1).See the diagram attached below to understand how to get the Q3 and Q1 of the data distribution.In conclusion, variability is a measure of IQR. The greater the IQR of a box plot, the greater the variety. Thus, the store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.

The five members of the traynor family each buy train tickets. During the train ride, each family member buys a boxed lunch for $6. 50. If the total cost of the trip is $248. 50, what is the price of each train ticket? enter your answer in the box
Answer:
Each ticket is $43.20
Explanation:
If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.
$6.50 × 5= $32.5
Now we subtract the meals from the total of $248.50.
$248.50 - $32.5= $216
All five tickets cost $216, now we divide this by 5 since five tickets were bought.
[tex]\frac{216}{5}[/tex]= $43. 2
Each ticket was $43.20
Let's double-check:
$32.5 + $43.20(5)= $32.5 + $216= $248.50

The electrolysis of molten AlCl3 for 4.25 hr having the current of 25Ampere will produces 35.67g of aluminum metal.
What is Electrolysis?Electrolysis can be described as the process where by electric current is passed through a substance to effect a chemical change.
The mass of the deposited metal can be calculated as
=[tex]W = CEt/96500[/tex]
Given;
t = time taken = 4.25hr
we can convert the time given from ( hrs) to secs as follows;
60secs=1 mins
60*60 secs = 1 hr
Then 25hrs= 4.25*60*60 = 15300s
C = Current = 25.0 A
E = Equivalent mass of Aluminum =9
Atomic-mass/valency = 27/3 = 9

The scientist wants to estimate the mean change in the density, in pounds per cubic inch, for each increase of 1 percent concentration of apple juice
The most appropriate inference procedure for the given investigation is;
A linear regression t-interval for the slope
What is the inferential statistic?We are told that the slope of an horizontal line is zero and that there is no change in the y (dependent) variable when there is a change in the x-variable. Thus, we need to find the true relationship between the two variables, 'x', and 'y'.
The confidence interval of the slope is calculated and analyzed to find out if it excludes or includes, 0. Thus, if the confidence interval excludes 0, then, it is unlikely that the slope is 0 and therefore the relationship between the variables, 'x', and 'y' is significant
In conclusion, a linear regression t-interval for the slope is most appropriate inference procedure.
