Question

Test the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats at the 0.1 significance level. The null and alternative hypothesis would be:

H0:μM=μFH0:μM=μF
H1:μM>μFH1:μM>μF
H0:pM=pFH0:pM=pF
H1:pM>pFH1:pM>pF
H0:pM=pFH0:pM=pF
H1:pM≠pFH1:pM≠pF
H0:μM=μFH0:μM=μF
H1:μM<μFH1:μM<μF
H0:μM=μFH0:μM=μF
H1:μM≠μFH1:μM≠μF
H0:pM=pFH0:pM=pF
H1:pM<pFH1:pM<pF

The test is:

right-tailed
left-tailed
two-tailed

Based on a sample of 40 men, 45% owned cats
Based on a sample of 40 women, 70% owned cats The test statistic is:  (to 2 decimals) The positive critical value is:  (to 2 decimals) Based on this we:

  • Reject the null hypothesis
  • Fail to reject the null hypothesis
