Problem 9

In Problems 9–12, conduct each test at the  = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, (c) the critical value, and (d) the P-value. Assume that the samples were obtained independently using simple random sampling.

9. Test whether p1 7 p2. Sample data: x1 = 368, n1 = 541, x2 = 351, n2 = 593

Step-by-Step Solution:

Step 1 of 5) In Problems 9–12, conduct each test at the = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, (c) the critical value, and (d) the P-value. Assume that the samples were obtained independently using simple random sampling. 9. Test whether p1 7 p2. Sample data: x1 = 368, n1 = 541, x2 = 351, n2 = 593. It is important to understand that subjective probabilities are perfectly legitimate and are often the only method of assigning likelihood to an outcome. As another example, a financial reporter may ask an economist about the likelihood the economy will fall into recession next year. Again, we cannot conduct an experiment n times to obtain a relative frequency. The economist must use her knowledge of the current conditions of the economy and make an educated guess about the likelihood of a recession.
