Calculate the test statistic and p-value for each sample. Use Appendix C-2 to calculate the p-value. (Negative values should be indicated by a minus sign. Round your test statistic to 3 decimal places and p-value to 4 decimal places.)

Test Statistic p-value
(a) H0: ππ ≤ .65 versus H1: ππ > .65, α = .05, x = 63, n = 84
(b) H0: ππ = .30 versus H1: ππ ≠ .30, α = .05, x = 16, n = 35
(c) H0: ππ ≥ .10 versus H1: ππ < .10, α = .01, x = 4, n = 116

During the period 1990–1998 there were 46 Atlantic hurricanes, of which 19 struck the United States. During the period 1999–2006 there were 70 hurricanes, of which 45 struck the United States. (a-1) Does this evidence convince you that the percentage of hurricanes that strike the United States is increasing, at α = .01? Let ππ 1 = proportion of hurricanes in United States from 1990-1998 and ππ 2 = proportion of hurricanes in United States from 1999-2006. Choose the correct...
