Question

data on the heights of 37 randomly selected female engineering students at UH:
62 64 61 67 65 68 61 65 60 65 64 63 59
68 64 66 68 69 65 67 62 66 68 67 66 65
69 65 69 65 67 67 65 63 64 67 65
We found that the sample mean and sample standard deviation for this sample data are 65.16 inches and 2.54 inches, respectively. Do you find sufficient evidence in the sample data to support the claim that the mean height of female engineering students at UH is greater than 65 inches at α = 0.05? Answer this question using both fixed-? approach and P-value approach. (Hint: for P-value approach, you need to find P-value range using the t-table as demonstrated in the lecture)
