14. Consider the following TI-84 display of a hypothesis test and answer the questions that follow. A) What are the null and alternate hypotheses? Use correct symbols to give your answer: B) What kind of test is conducted here? Circle one: Left-tailed Right tailed Two-tailed C) What is the sample size? D) What is the value of the test statistic? E) What is the P-value? F) Should you reject the null hypothesis at the 0.05 level? G) Should you reject the null hypothesis at the 0.01 level? Should reject null hypothesis at the 0.05 level since p value is less than 0.05 Should not reject mdl hypothesis et the 0.01 level since p value is more then 0.01

Solution

H0: p1 = p2

Ha: p1 > p2

(p1, p2 are proportions for two samples to be compared)

b) Right tailed

c) sample size = 280

d) Test statistic z = 1.676803364

e) p value = 0.6392857143

f) p value >alpha. Hence should not reject null hypothesis.

g) Should not reject null hypothesis as p >0.1
