a. Test the claim using a hypothesis test. Consider the rst sample to be the sample of males and the second sample to be the sample of females. What are the null and alternative hypotheses for the hypothesis test? \"0:91:92 v H05p1=p2 H03p1=P2 H15p1p2 H15p192 Ho5p1p2 \"0591392 H03p15F'2 \"1:91:92 H15P1pz H15P1Pz Identify the test statistic. Z: -0.42' (Round to two decimal places as needed.) Identify the Pvalue. PValue = (1337' (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is greater than the signicance level ofoi = 0.05, so fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the rate of left-handedness among males is less than that among females. b. Test the claim by constructing an appropriate confidence interval. The 90% condence interval is - 0.049' P2 H13P1=F'2 Ho3p1=p2 Ho3p1=p2 H03p1292 H15p1
