EQuestion Help In a random sample of males, it was found that 27 write with their left hands and 216 do not. In a random sample of females, it was found that 72 write with their left hands and 455 do not. Use a 0.01 significance level of left-handedness among males is less than that among females. Complete parts (a) through (c) below. test the claim that the rate a. Test the claim using a hypothesis test. Consider the first sample to be the sample of males and the second sample to be the sample females. What are the null and alternative hypotheses for the hypothesis test? OC. Ho: P1 SP2 O A. Ho: P, 2 P2 H: P P2 OB. Ho: P1 = P2 H P +P2 H,: P, #P2 OF. Ho: P =P2 H: P, P2 H,:P, =P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? V the null hypothesis. There V evidence to support the claim that the rate of left-handedness among males is less than that among females. The P-value is V the significance level of a = 0.01, so b. Test the claim by constructing an appropriate confidence interval. The 98% confidence interval is< (P, -P2)
