Answer:
1) With H1: p ≠ 3/5, the test statistic is z = 0.78
The p value for this case would be given by:
Best option:
A) 0.4354; fail to reject the null hypothesis
2) The test statistic in a left-tailed test is z = -1.83
The p value for this case would be given by:
Best option:
A) 0.0336; reject the null hypothesis
3) The test statistic in a right-tailed test is z = 0.52.
The p value for this case would be given by:
Best option:
C) 0.3015; fail to reject the null hypothesis
Step-by-step explanation:
The significance level for all the cases is the same
Part 1
With H1: p ≠ 3/5, the test statistic is z = 0.78
The p value for this case would be given by:
Best option:
A) 0.4354; fail to reject the null hypothesis
Part 2
The test statistic in a left-tailed test is z = -1.83
The p value for this case would be given by:
Best option:
A) 0.0336; reject the null hypothesis
Part 3
The test statistic in a right-tailed test is z = 0.52.
The p value for this case would be given by:
Best option:
