Consider the following. (Give your answers correct to two decimal places.)

(a) Calculate the test statistic z used in testing Ho: p = 0.70, Ha: p > 0.70; with the sample n = 304 and x = 250.

(b) Calculate the test statistic z used in testing Ho: p = 0.50, Ha: p < 0.50; with the sample n = 462 and x = 210.

(c) Calculate the test statistic z used in testing Ho: p = 0.35, Ha: p ≠ 0.35; with the sample n = 295 and x = 93.

(d) Calculate the test statistic z used in testing Ho: p = 0.90, Ha: p > 0.90; with the sample n = 550 and x = 517.

You may need to use the appropriate table in Appendix B to answer this question.

Answer #1

(a)

= 250 / 304 = 0.8224

(b)

= 210 / 462 = 0.4545

(c)

= 93 / 295 = 0.3152

(d)

= 517 / 550 = 0.94
