Question: (2 points) A sample of 8 measurements, randomly selected from a normally distributed population, resulted in a sample mean, I = 7.9 and sample standard

(2 points) A sample of 8 measurements, randomly selected from a normally distributed population, resulted in a sample mean, I = 7.9 and sample standard deviation s = 1.25. Using o = 0.05, test the null hypothesis that the mean of the population is 8.5 against the alternative hypothesis that the mean of the population, u >: 8.5 by giving the following: (a) the degree of freedom (b) the critical t value (c) the test statistic The final conclusion is O A. There Is not sufficient evidence to reject the null hypothesis that ju = 8.5. O B. We can reject the null hypothesis that / = 8.5
