Question

Additionally, find p-value, test the claim by constructing an appropriate confidence interval, and, Use this information to determine whether the rate of​ left-handedness among males is less than the rate of​ left-handedness among females.

In a random sample of males, it was found that 23 write with their left hands and 221 do not. In a random sample of females, it was found that 72 write with their left
hands and 468 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. Test the claim using a hypothesis 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?
O A. Ho: P1 = P2
H1: P1 > P2
B. Ho: P1 = P2
H1:P1 <P2
O C. Ho: P1 SP2
H1: P1 # P2
O D. Ho: P1 # P2
H1: P1 = P2
E. Ho: P1 = P2
H1: P1 # P2
O F. Ho: P1 2 P2
H1: P1 #P2
Identify the test statistic.
(Round to two decimal places as needed.)
