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
Answer:
The missing measurement is 9 miles
Step-by-step explanation:
we know that
The Area of a parallelogram is equal to
where
b is the length of any base
h is the corresponding altitude
The altitude (or height) of a parallelogram is the perpendicular distance from the base to the opposite side (which may have to be extended).
In the figure, the altitude corresponding to the base is 4 miles
substitute
Solve for b
Divide by 4 both sides
therefore
The missing measurement is 9 miles
