In a random sample of males, it was found that 18 write with their left hands and 215 do not. In a random sample of females, it was found that 65 write with their left hands and 448 do not. Use a 0.05 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. ▾ The 90% confidence interval is < (P1-P2) < (Round to three decimal places as needed.). What is the conclusion based on the confidence interval? Because the confidence interval limits.

In a random sample of males, it was found that 18 write with their left hands and 215 do not. In a random sample of females, it was found that 65 write with their left hands and 448 do not. Use a 0.05 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. The 90% confidence interval is (P₁-P₂) <L (Round to three decimal places as needed.)
