Test the claim that the proportion of men who own cats is larger than 60% at the .05 significance level.

The null and alternative hypothesis would be:

\displaystyle {H}_{{0}}:\mu={0.6}

\displaystyle {H}_{{1}}:\mu≠{0.6}

\displaystyle {H}_{{0}}:{p}={0.6}

\displaystyle {H}_{{1}}:{p}>{0.6}

\displaystyle {H}_{{0}}:{p}={0.6}

\displaystyle {H}_{{1}}:{p}<{0.6}

\displaystyle {H}_{{0}}:{p}={0.6}

\displaystyle {H}_{{1}}:{p}≠{0.6}

\displaystyle {H}_{{0}}:\mu={0.6}

\displaystyle {H}_{{1}}:\mu<{0.6}

\displaystyle {H}_{{0}}:\mu={0.6}

\displaystyle {H}_{{1}}:\mu>{0.6}

The test is:

two-tailed

right-tailed

left-tailed

Based on a sample of 100 people, 67% owned cats

The test statistic is: (to 2 decimals)

The critical value is: (to 2 decimals)

Based on this we:

Fail to reject the null hypothesis
Reject the null hypothesis
