I keep getting the positive  critical value wrong 

Test the claim that the proportion of men
who own cats is significantly different than
90% at the 0.01 significance level.
The null and alternative hypothesis would
be:
Но : р — 0.9 Но: р
Н:р < 0.9 Н,:р+0.9 Hi:n< 0.9
0.9 Ho: µ = 0.9
Ho: u
0.9 Но:и
0.9 Но: р — 0.9
Н:р > 0.9 Н,:р + 0.9 Hi:р> 0.9
The test is:
left-tailed right-tailed two-tailed
Based on a sample of 65 people, 98%
owned cats

Based on a sample of 65 people, 98%
owned cats
The test statistic is:
2.15
(to 2 decimals)
The positive critical value is:
|(to 2 decimals)
Based on this we:
| Fail to reject the null hypothesis
| Reject the null hypothesis
