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 (to 3 decimals) (to 2 decimals)
