a. Here we see that alternative hypothesis have inequality sign, which means it is two tailed test
Hence answer is This is two tailed test
b. z test statistics is z=2.95, so P value is
c. As P value is less than , we reject the null hypothesis
So answer here is D. Reject Upper H0. There is sufficient evidence to support the claim that p not equals≠0.497.

In a previous year, 5656% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 750750 females aged 15 and older and finds that 410410 are living alone. Is there sufficient evidence at the alphaαequals=0.10.1 level of significance to conclude the proportion has changed?
