A sample of birth weights of 25 girls was taken. Below are the results (in g): 1921.1 2628 2905.3 2721.1 3405.6 3432.9 3099 2561.6 3260.9 1728 3072 1624.1 3275.6 2212.2 2904 3405.8 2772.4 4251.3 3134.2 4637 2887.9 2567.8 3428 2235.6 1826.3 2875.9 g 8= 726.66 g Use a 10% significance level to test the claim that the standard deviation of birth weights of girls is greater than the standard deviation of birth weights of boys, which is 500 g. Round all answers to 3 decimal places if possible. Procedure: One standard deviation x Hypothesis Test Step 1. Hypotheses Set-Up: Ho: av I teett H₁: ov The test is a right-tailed = 500 >v Left CV- - Right CV- 500 test. h Step 2. The significance level is a = Step 3. Compute the value of the test statistic: Round this answer to 2 decimal places. X² Step 4. Testing Procedure: Provide the critical value(s) for the Rejection Region. For a one-tailed test, use DNE for the unneeded critical value. Round to 3 decimal places.
