n a random sample of males, it was found that 17 write with their left hands and 218 do not. In a random sample of females, it was found that 56 write with their left hands and 449 do not. Use a 0.01 significance level to test the claim that the rate of left-handeness among males is less than that among females. Complete parts (a) through (c) below. a. test the claim using the 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 hypothesis for the hypothesis test? Identify the test statistic. Identify the P-value. What is the conclusion based on the hypothesis test? b. test the claim by constructing an appropitae confidence interval The 98% confidence interval is _ < (p1 - p2) < _ c. based on the results, is the rate of left handeness among males less than the rate of left handeness among females?

Identify the test statistic.
Identify the P-value.
What is the conclusion based on the hypothesis test?
b. test the claim by constructing an appropitae confidence interval
