The test is:
left-tailed
two-tailed
right-tailed
Based on a sample of 400 people, 80 owned cats
What is p̂ (to 2 decimal places)?
The test statistic is: (to 2 decimals)
The p-value is: (to 4 decimals, if your p-value is less than 0.0001, you may enter 0))
Based on this we:
- Fail to reject the null hypothesis
- Reject the null hypothesis
