In a random sample of males, it was found that 24 write with their left hands and 222 do not. In a random sample of females, it was found that 68 write with their left hands and 457 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.
