Step-by-step explanation:
Let the cost of each shirt be x.
Would assume each shirt was discounted by 3.66
Amount to be paid for each : x - 3.66
Total = 3*(x - 3.66)
3*(x - 3.66) = 62.31
x - 3.66 = 62.31/3
x - 3.66 = 20.77
x = 20.77 + 3.66
x = 24.43
Each shirt cost $24.43 before the discount.

Answer:
When all possible differences between pairs of population means are evaluated not with an F test, but with a series of regular t tests, the probability of at least one:
A. type I error is larger than the specified level of significance.
B. type II error is larger than the specified level of significance.
C. type I error is smaller than the specified level of significance.
D. type II error is smaller than the specified level of significance.
Answer : Type I error is larger than the specified level of significance.( A )
Step-by-step explanation:
An F test is a test that is used to test whether the variances between pairs of populations are equal while a T test is a test used to check if a pair of population are equal not considering the fact that the variances of the population are different .
When a T test is used to evaluate all possible differences between pairs of population instead of F test there is a probability of atleast one type 1 error larger than the specified level of significance.
