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 = %3D • Right CV = The p-value is Link E to Chi-Square Table: https://www.itl.nist.gov/div898/handbook/eda/section3/ed Step 5. Decision Is the test statistic in the rejection region? ? Is the p-value less than the significance level? ? Conclusion: Select an answer Step 6. Interpretation: At a 5% significance level we Select an answer have sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.

A sample of birth weights of 48 girls was taken. Below are the results (in g): 2724.5 3340.1 3243.6 3442.1 2996.9 3042 3505 3161.8 4022.8 3362.9 3768.9 2951.9 3229.7 2997.5 3758.1 3350.2 3210.7 3684.3 3530.1 3132.7 2776.9 3492.7 2655.1 3790.9 3064.6 3744.6 3294.5 2654.7 3536.6 2781.1 3756.3 3531.5 3654.2 3505.1 4018.6 3038 3202.3 3006 3701.6 3451.4 2986.5 3541.2 3232.9 2966 3186 3550.3 3056.6 3467.1 * = 3314.6 g s = 347.35 g Use a 5% significance level to test the claim that the standard deviation of birth weights of girls is less than the standard deviation of birth weights of boys, which is 530 g. Round all answers to 3 decimal places if possible.
