Transcribed Image Text:Test the claim that the proportion of men who own cats is smaller than 30% at the .10 significance level.
The null and alternative hypothesis would be:
Ho: μ = 0.3
H₁:μ0.3
O Ho : p = 0.3
H₁:p> 0.3
Ο Η : μ = 0.3
Η : μ < 0.3
O Ho: p= 0.3
H₁: p0.3
Ο Ηo : μ = 0.3
H : μ > 0.3
○ Ho: p=0.3
H₁: p<0.3
Based on a sample of 65 people, 27% owned cats
The test statistic is
The critical value is
Based on this we
O Reject the null hypothesis
O Fail to reject the null hypothesis
