Test the claim that the proportion of men who own cats is larger than 90% at the 0.10 significance level.
The null and alternative hypotheses would be:
H0: p = 0.9
H1: p > 0.9
H0: p = 0.9
H1: p < 0.9
H0: p = 0.9
H1: p ≠ 0.9
H0: p = 0.9
H1: p < 0.9
H0: p = 0.9
H1: p ≠ 0.9
H0: p = 0.9
H1: p > 0.9
The test is:
left-tailed
two-tailed
right-tailed
Based on a sample of 45 people, 92% owned cats.
The test statistic is: (to 2 decimals)
The critical value is: (to 2 decimals)
Based on this, we:
Reject the null hypothesis
Fail to reject the null hypothesis
