In a random sample of males, it was found that 25 write with their left hands and 217 do not. In a randorm sample of females, it was found that 58 write with their left hands and 451 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. Identify the test statistic. 43 (Round to two decimal places as needed.) Identify the P-value. P-value = 334 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is greater than the significance level of a= 0.01, 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 98% confidence interval is < (P1- P2) < (Round to three decimal places as needed.)
