Question

From previous studies, it is concluded that 48% of people support stricter gun laws. A researcher claims it has decreased and decides to survey 100 adults. Test the researcher's claim at the $\alpha = 0.05$ significance level Preliminary: a. Is it safe to assume that $n \leq 0.05$ of all subjects in the population? Yes No b. Verify $np(1 - p) \geq 10$. Round your answer to one decimal place. $np(1 - p) =$ Test the claim: a. Express the null and alternative hypotheses in symbolic form for this claim. $H_0:$ $H_a:$ b. After surveying 100 adult Americans, the researcher finds that 34 people support stricter gun laws. Compute the test statistic. Round to two decimal places. $z = $ c. What is the p-value? Round to 4 decimals. $p = $
