In a random sample of males, it was found that 20 write with their left hands and 224 do not. In a random sample of fermales, it was found that 63 write with their left hands and 439 do not. Use a 0.01 significance level to test the claim that the rate of left-handedness among males is less than that armong fernales. Complete parts (a) through (c) below (ROunI TO TWO ORCIma praces as needea Identify the P-value. P-value = 0.040 (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 (Round to three decimal places as needed.)

Use a 0.01 significance level to test the claim that the rate of left-handedness among males is less than that arrmong females. Complete parts (a) through (c) below. (ROun 0 wO OBCimar piaces as neededJ Identify the P-value. P-value = 0.040 (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.
