You wish to test the following claim (𝐻𝑎) at a significance level of 𝛼=0.001.
$$H_o:\mu<=53.8$$
$$H_a:\mu>53.8$$
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
a sample of size n = 9 with a mean of M = 61.7and a standard deviation of SD = 7.2
