A sample of five measurements, randomly selected from a normally distributed population, resulted in the following summary statistics:
a.Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, μ<6. Use α = .05.
b.Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, μ ≠ 6.Use α = .05.
c.Find the observed significance level for each test.
