Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .005 significance level.
the null and alternative hypothesis would be:
h0: pm=pfh0: pm=pf
h1: pm
h0: μm=μfh0: μm=μf
h1: μm> μfh1: μm> μf
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:
two-tailed
right-tailed
left-tailed
based on a sample of 40 men, 25% owned cats
based on a sample of 40 women, 35% 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
