Solution :
Given :
Sample mean,
Sample size, n = 40
Standard deviation, s = 83.2
∴ The null hypothesis is
Alternate hypothesis is
Test statistic :
z = 0.813
Now at α = 0.05, for a right tailed,
Since, , we fail to reject the null hypothesis.
7 1/2 x 3 3/4 x 2, to get the answer. The answer is
56 1/4 feet squared
Answer:
