A survey found that 39% of 815 randomly sampled teens said that their parents checked to see what websites they visited. The following year, the same question posed to 807 teens found 40% reporting such checks. Do these results provide evidence that more parents are checking?
Let p1 and p2 be the proportions of parents checking the websites visited in the first and second years, respectively. Choose the correct null and alternative hypotheses below. Determine the test statistic. Find the P-value. State the result of this hypothesis. Assume alpha α equals 0.05.
