Question

(a) Write the claim mathematically and identify H_0 and H_a. (b) Find the critical value(s) and identify the rejection region(s). (c) Find the standardized test statistic. (d) Decide whether to reject or fail to reject the null hypothesis. In a sample of 1788 home buyers, you find that 757 home buyers found their real estate agent through a friend. At alpha = 0.08, Can you reject the claim that 47% of home buyers find their real estate agent through a friend? (a) Which of the following correctly states H_0 and H_a? A. H_0: p = 0.47 H_a: p notequalto 0.47 B. H_0: p = 0.47 H_a: p > 0.47 C. H_0: p

Explanation / Answer

Z0=-1.75, 1.75

Test statistic z=(757/1788-0.47)/sqrt(0.47*(1-0.47)/1788)= -3.9499

Reject the null hypothesis
