In a random sample of males, it was found that 22 write with their left hands and 220 do not. In a random sample of females, it was found that 70 write with their left hands and 452 don 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. z = -1.71 (Round to two decimal places as needed.) Identify the P-value. P-value= 0.044 (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 < (P-P₂) < (Round to three decimal places as needed.)

Q
In a random sample of males, it was found that 22 write with their left hands and 220 do not. In a random sample of females, it was found that 70 write with their left hands and 452 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.

P-value=0.044
(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 α = 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 < (P-P₂)<
(Round to three decimal places as needed.)
