Test the claim that the proportion of people who own cats is smaller than 80% at the 0.01 significance level.
The null and alternative hypothesis would be:
H0: p ≥ 0.8
H1: p < 0.8
H0: p = 0.8
H1: p ≠ 0.8
H0: p ≥ 0.8
H1: p < 0.8
H0: p ≤ 0.8
H1: p > 0.8
H0: p = 0.8
H1: p ≠ 0.8
H0: p ≤ 0.8
H1: p > 0.8
The test is:
right-tailed
left-tailed
two-tailed
Based on a sample of 600 people, 74% owned cats.
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this, we:
Fail to reject the null hypothesis
Reject the null hypothesis
