In a random sample of males, it was found that 26 write with their left hands and 212 do not. In a random sample of females, it was found that 72 write with their left hands and 438 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.
a. lest the claim using a nypothesis test.
Consider the first sample to be the sample of males and the second sample to be the sample of females. What are the null and alternative hypotheses for the hypothesis test?
OA. Ho: P₁ SP2
OD. Ho: P1 P2
H₁: P₁ = P2
Identify the test statistic.
z = -1.21
(Round to two decimal places as needed.)
Identify the P-value.
P-value = 0.113
(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.)
