5 CH 9,IU) 1 Saveu Help Save & Exit Submit 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 2 decimal places and p-value to 4 decimal places.) Test Statistic p-value (a) HO: 13.60 versus H1: >.60, a = .05, x = 56, n = 80 (b) H0: = .30 versus 11: 17.30, a = .05, x = 18, n = 40 (c) Ho: 12.10 versus H]: 1 <.10, a - .01, X - 3, n = 100 3:49:34 Book Hint rences

Answer 1

The statistical software outputs for this problem is:

One sample proportion summary hypothesis test: P: Proportion of successes Ho: P = 0.6 HA: p > 0.6 Hypothesis test results: Proportion Count Total Sample Prop. Std. Err. Z-Stat 56 80 0.7 0.054772256 1.8257419 P-value 0.0339

One sample proportion summary hypothesis test: P: Proportion of successes Ho : p = 0.3 HA: P0.3 Hypothesis test results: Proportion Count Total Sample Prop. Std. Err. Z-Stat 18 40 0.45 0.072456884 2.0701967 P-value 0.0384

One sample proportion summary hypothesis test: p: Proportion of successes Ho : P = 0.1 HA: P < 0.1 Hypothesis test results: Proportion Count Total Sample Prop. Std. Err. Z-Stat 3 100 0.03 0.03 -2.3333333 P-value 0.0098

Hence,

a) Test statistic = 1.83

P - value = 0.0339

b) Test statistic = 2.07

P - value = 0.0384

c) Test statistic = -2.33

P - value = 0.0098
