What’s the minimum number of people you have to ask?
>> One person
>> Two people
>> Three people
>> Four people
Which people do you ask?
>> Anne

Two people, Anne and Charlie.
StatisticsGiven that Anne is 35 years old, Bob is 24 years old, Charlie has feature A, and Daniel doesn't have feature A, and you want to conclusively test the hypothesis “among these four people, those above age 30 definitely have feature A ”, to determine what's the minimum number of people you have to ask and which people do you ask, the following calculation must be performed:
Of the 4 people, 1 is over 30 years old and another has feature A, with which both should be considered for the study, while the other two do not meet the requirements. So, these two people would be Anne and Charlie.

Find five numbers so that the mean, median, mode and range is 4.
Answer:
Let’s break this apart
Well we know the median has to be 4
Since it’s 5 numbers the middle number has to be 4 since its the median.
Let’s put in what we know.
a, b, 4, d, e
Constraints:
There has to be more then 1 “4”.
e-a = 4
So using that information lets solve since the possibility is almost endless
SO lets make e 5 and a 1.
1, b, 4, d, 5
There has to be more then 1 4 so lets put that as b.
We can solve for the last remaining digits.
1+ 4 + 4 + d + 5 / 5 = 4
14 + d /5 = 4
2.2 + d = 4
1.8 = d
So now if we put in order and replace b with 1.8 and make d as the previous “b” as 4.
1, 1.8, 4, 4, 5
Thats your 5 numbers right there.
Check:
Mode is 4: yes!
Range is 4: 5-1 = 4 yes!
Median is 4: yes!
Mean is 4: 1 + 1.8 + 4 + 4 +5 / 5 = 4 yes!
Every thing checks out.
There could be a lot of possibilities.
For example take this wrong one
Lets make the same exact thing except change the a and the e.
THis is what we have,
a, b, 4, d, e
Lets make e and a as 6 and 2. 6-2 is still 4 so its possible.
2, b, 4, d, 6
And of course we need more then 1 4 so lets make d 4.
2, b, 4, 4, 6
Now solve for b in the mean.
2 + b + 4 + 4 + 6 / 5 = 4
16 +b /5 = 4
3.2 + b = 4
Solve
B = 0.8
This doesn’t work cause the median and the range has constraint here…
When doing a median, it has to be in ORDER.
2, 0.8, 4, 4 , 6 isn’t in order
ANd even when put in order.
0.8, 2, 4, 4, 6
THe range has the constraint here becuase 6 - 0.8 isn’t 4.

How do you convert 3 1/3 yards to inches? Use the drop-down menus to explain your answer.
Since, there are 36 inches in 1 yard, multiply 3 1/3 by 36
So, 3 1/3 yards = 120 inches
Answer:
120 inches
Step-by-step explanation:
To convert 3 1/3 yards to inches, you first need to figure out how many inches are in one yard. 1 yard=36 inches.
After this, you would turn your mixed fraction into an improper fraction and then multiply by 36 inches. It would look like this:
10/3 * 36/1
Here, you would cancel out the common factors by factoring 36 by 3.
12*3=36 ----> 10/3 * [tex]\frac{3(12)}{1}[/tex] ----->
Lastly, multiply 10 by 12 and your answer would be 120 inches.

a baby weights 7 pounds at birth. the table shows the birth weight after each month of life, up to six months
Answer:
y = 1x + 7
Step-by-step explanation:
Let's take 2 points, with x being the month and y being the weight as the month is listed first in the graph.
(0, 7) = the 1st point
(1, 8) = the 2nd point
In y=mx+b, m is the slope.
Slope = change in y / change in x = (y₂-y₁) /(x₂-x₁) = (y₁-y₂) / (x₁-x₂) = (8-7)/(1-0) = 1 / 1 = 1 = (7-8)/(0-1) = -1/-1 = 1
Our equation is thus
y = mx + b = y = (1) x + b
Plug one point, such as (1, 8) into this equation to obtain b
8 = (1) (1) + b
8 = 1 + b
subtract 1 from both sides to isolate b
7 = b
our equation is thus
y = (1) x + 7 = 1x + 7
Answer:
w = 1m + 7
Step-by-step explanation:
w = weight
m = months
If we look at the chart, as every month goes by, the baby gains another pound.
Hence, the best way to find the weight is to just add 7 to the months, since in the beginning (at 0 months) the weighs 7 pounds, so if it’s 1 month, the baby would just way 1 more pound.
This is why the formula: w = 1m + 7 works
Because 1 times the value of any month will be the same value, and all you have to do is add 7.
Example:
(x = multiply in this equation)
At 2 months: w = 1 x 2 + 7
Solve:
1 x 2 = 2
2 + 7 = 9
As you can see, all you have to do is fill in the month # in the formula, and you will get your w (weight).
Hope this helps :)

Describe and correct the error in using the percent proportion to answer the question below
“6 is 6.25% of what number”
Using proportions, it is found that the error was treating the 100% value as a percent(100) instead of a decimal 1, hence the correct value is of 96.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that 100% = 1 of the number is w, while 6 is equals to 6.25% = 0.0625. Hence the rule of three is given by:
1 - w
0.0625 - 6
Applying cross multiplication:
0.0625w = 6.
w = 6/0.0625
w = 96.
The error was treating the 100% value as a percent(100) instead of a decimal 1, hence the correct value is of 96.

Ciara, an ornithologist, has 444 bird feeders at separate locations. She wonders if birds are equally likely to visit each of the feeders. She recorded data for a sample of 350350350 recent visits. Here are the results: Feeder \#1#1\#, 1 \#2#2\#, 2 \#3#3\#, 3 \#4#4\#, 4 Observed visits 808080 909090 929292 888888 Ciara wants to perform a \chi^2χ 2 \chi, squared goodness-of-fit test to determine if these results suggest that birds visit one specific feeder more often than the other feeders. What is the expected count of visits to the third feeder? You may round your answer to the nearest hundredth.
The expected count of visits is the mean or average visits to each feeder
The expected count of visits to the third feeder is 87.5
How to determine the expected count of visit?The table of values is given as:
Feeder 1 2 3 4
Observed visits 80 90 92 88
In this case, the null hypothesis implies that the visits to each feeder are uniformly distributed
So, the expected count is calculated using:
Expected count =Visits/Feeders
This gives
Expected count = 350/4
Evaluate the quotient
Expected count = 87.50
Hence, the expected count of visits to the third feeder is 87.5
