(1 point) A sample of 8 measurements, randomly selected from a normally distributed population, resulted in a sample mean, 3 = 7.9 and sample standard deviation s = 1.04. Using a = 0.01, test the null hypothesis that the mean of the population is 7.3 against the alternative hypothesis that the mean of the population, we > 7.3 by giving the following: (a) the degree of freedom (b) the critical value (c) the test statistic The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that u = 7.3. B. We can reject the null hypothesis that = 7.3 and accept that u < 7.3.
