Problem 1:
a) The null hypothesis (H0) and the alternate hypothesis (HA) has been stated as
follows:
Ho: μ ≤ 0.75
HA: μ >0.75
The test statistic for this test can be given by the following formula:
t= X−μ
σ
√ n
Here, X is the sample mean, μ is the mean value that has been hypothesized, σ is the standard
deviation of the sample and n is the sample size. In this study,
Sample mean ( X ) = 0.68
