Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.
Let represents the population mean .
Then, the set of hypothesis will be:-
We assume that this is normal distribution.
Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.
Sample mean :
Standard deviation :
The test statistic for population mean for small sample is given by :-
Hence , the value of test statistic = 1.460
The midpoint of AB is point G
<h2>Explanation:</h2>The complete question has been attached below. As you can see, we have a line segment which is defined as a part of a line that is bounded by two different points that are at the end of the segment. So here we know that:
- A is located at point -6.
- B is located at point 8
Therefore, the midpoint can be calculated as:
So the midpoint is that matches point G. Finally:
Conclusion: The midpoint of AB is point G
