In a random sample of males, it was found that 23 write with their left hands and 212 not. In a random sample of females, it was found that 58 write with their left hands and 442 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. 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? OA. Ho: P₁ P₂ H₁: P₁ P₂ OD. Ho: P₁ P2 H₁: P₁ P₂ Identify the test statistic. OB. Ho: P₁ P2 H₁: P₁ P2 The P-value is hypothesis. There OE Ho: P₁ P2 H₁: P₁ =P₂ (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The 90% confidence interval is < (P₁-P₂)< (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? OC. Ho: P₁ P2 H₁: P₁ P₂ the significance level of a = 0.05, so evidence to support the claim that the rate of left-handedness among males is less than that among females. b. Test the claim by constructing an appropriate confidence interval. Because the confidence interval limits OF. Ho: P1 P2 H₁: P₁ P₂ there the null to be a significant difference between the rates of left-handedness
