ha random sample of males, it was found that 22 write with their left hands and 207 do not. In a random sample of females, it was found that 61 write with their left hands and 433 do not. Use a 0.05 significance level to test the claim that the rate of left-handedness among males is less than thất amoh
emales. 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?
