Question
Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .10 significance level.
The null and alternative hypothesis would be:
H0:pM=pFH0:pM=pF
H1:pM>pFH1:pM>pF
H1:pM>pFH1:pM>pF
H0:μM=μFH0:μM=μF
H1:μM<μFH1:μM<μF
H1:μM<μFH1:μM<μF
H0:μM=μFH0:μM=μF
H1:μM≠μFH1:μM≠μF
H1:μM≠μFH1:μM≠μF
H0:pM=pFH0:pM=pF
H1:pM≠pFH1:pM≠pF
H1:pM≠pFH1:pM≠pF
H0:μM=μFH0:μM=μF
H1:μM>μFH1:μM>μF
H1:μM>μFH1:μM>μF
H0:pM=pFH0:pM=pF
H1:pM<pFH1:pM<pF
H1:pM<pFH1:pM<pF
The test is:
left-tailed
two-tailed
right-tailed
Based on a sample of 40 men, 35% owned cats
Based on a sample of 20 women, 45% owned cats
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we:
- Fail to reject the null hypothesis
- Reject the null hypothesis
