QUESTION

(1 pt) The point of this problem is to get you used to using the table of critical values to do hypothesis tests when you don’t have software available that will calculate the preciseP-value associated to your test statistic.A sample of 9 measurments, randomly selected from a normally distributed population, resulted in a sample mean, x¯=6.5 and sample standard deviation s=1.45. Using α=0.01, test the null hypothesis that the mean of the population is μ=8.3 against the alternative hypothesis that the mean of the population satisfies μ<8.3. Find:(a) the degree of freedom (b) the critical t∗ value (To do this you will need to use the degree of freedom and the significance level to find the critical value in the table). (c) the t test statistic To make a final conclusion you need to compare the t test statistic to the critical t value.The final conclustion is A. There is not sufficient evidence to reject the null hypothesis that μ=8.3. B. We can reject the null hypothesis that μ=8.3 and accept that μ<8.3.   ANSWER: REQUEST HELP FROM A TUTOR
