A sample of 8 measurements, randomly selected from a normally distributed population, resulted in a sample mean, = 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, μ> 7.3 by giving the following: (a) the degree of freedom (b) the critical f value (c) the test statistic The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis that μ = 7.3. OB. We can reject the null hypothesis that = 7.3 and accept that μ< 7.3.
