H0:μ≥0.8H0:μ≥0.8
H1:μ<0.8H1:μ<0.8
H1:μ<0.8H1:μ<0.8
The test is:
left-tailed
right-tailed
two-tailed
Based on a sample of 700 people, 74% owned cats
The test statistic is: (to 2 decimals)
The critical value is: (to 2 decimals)
Based on this we:
- Fail to reject the null hypothesis
- Reject the null hypothesis
