In a random sample of males, it was found that 28 write with their left hands and 227 do not. In a random sample of females, it was found that 66 write with their left hands and 442 do not. Use a 0.01 si to test the claim that the rate of left-handedness among males is less than that among females. Complete parts (a) through (c) below. O A. Ho: P1 2 P2 H1: P1 #P2 O B.

Question
In a random sample of males, it was found that 28 write with their left hands and 227 do not. In a random sample of females, it was found that 66 write with their left hands and 442 do not. Use a 0.01 significance level to test the claim that the rate of left-handedness among males is less than that among females. Complete parts (a) through (c) below. O A. Ho: P1 2 pP2 H1: P1 #P2 O B. Ho: P1 *P2 H1: P1 = P2 OC. Ho: P1 sp2 H1: P1 #P2 O D. Ho: P1 = P2 H: P1 <P2 O E. Ho: P1 = P2 H1: P1 > P2 OF. Ho: P1 = P2 H: P1 #P2 Identify the test statistic. z=D (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 The P-value is V the significance level of a = 0.01, so among females. b. Test the claim by constructing an appropriate confidence interval. The 98% confidence interval is O< (P1 - P2) <U (Round to three decimal places as needed.) What is the conclusion based on the confidence interval?
