You believe the population is normally distributed and you know the standard deviation is σ = 6.9 σ = 6.9 . you obtain a sample mean of m = 64.4 m = 64.4 for a sample of size n = 32 n = 32 . what is the critical value for this test?

answer:

your answer is: c. 196 7/8 in^3.

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.
