A sample of 5 measurements, randomly selected from a normally distributed population, resulted in a sample mean, x¯¯¯=6.9 and sample standard deviation s=1.28. Using α=0.05, test the null hypothesis that the mean of the population is 7.7 against the alternative hypothesis that the mean of the population, μ<7.7 by giving the following:
find:
(a) the degree of freedom:
(b) the critical t value:
(c) the test statistic:
