*Show ALL work, answer is given already*

Answer 1

Answer #1

Solution,

degrees of freedom = n - 1 = 12 - 1 = 11

This is left tailed test,

a) Test statistic = 2.05

P(t < 2.05 )

P-value = 0.9675

b) Test statistic = -1.84

P(t < -1.84 )

P-value = 0.0464

c) Test statistic = 0.4

P(t < 0.4 )

P-value = 0.6516

Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the alternative that it is not at a level of significance of 5% and a sample size of n=151. We calculate a test statistic = -1.976. The p-value of this hypothesis test is approximately ? . (Write your answer out to two decimal places. In other words, write 5% as 0.05.)
