3304.2 8 620.82 s Use a 5% significance level to test the claim that the standard deviation of birth weights of girls is different from the standard deviation of birth weights of boys, which is 470 g. Round all answers to 3 decimal places if possible. Procedure: One variance y* Hypothesis Test v Step 1. Hypotheses Set-Up: Hạ: G v= 470 H: G 470 The test is a two-taled v test. Step 2. The significance level is a = 0.05 Step 3. Compute the value of the test statistic: X 61.087 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. • Left CV= Right CV = The p-value is Link to Chi-Square Table: https://www.itl.nist.govidiv898/handbook/eda/section3/eda3674.htm Step 5.
