A physiological experiment was conducted to study the effect of various factors on pulse rate. For one factor, there were 92 subjects, the mean pulse rate of which was 72.87, and the sample standard deviation was 11.01. Consider the following hypotheses:
i. H0: ? =75 vs. Ha: ? > 75,
ii. H0: ? =75 vs. Ha: ? ? 75
where ? is the population mean.
a) Compute the p-value for each test .
b) State the conclusion based on the 5% level of significance.
