Question
(1 point) A sample of 9 measurements, randomly selected from a normally distributed population, resulted in a sample mean x 6.1 and sample standard deviation s = 1.82. Using 0.01, test the null hypothesis that the mean of the population is 5.4 against the alternative hypothesis that the mean of the population is less than 5.4 by giving the following (a) the degree of freedom (b) the critical t value (c) the test statistic The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis that 5.4. B. We can reject the null hypothesis that 54.Explanation / Answer
