I need help with answering the questions after identifying the P-value. What is the conclusion based on the hypothesis test?V the significance level of a = 0.01, soV the null hypothesis. ThereV sufficient evidence to support the claim that the fatality rate is higher forThe P-value isthose not wearing seat belts.b. Test the claim by constructing an appropriate confidence interval.The appropriate 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 limitsV0, it appears that the two fatality rates areBecause the confidence interval limits includevalues, it appears that the fatality rate isfor those not wearing seat belts.c. What do the results suggest about the effectiveness of seat belts?O A. The results suggest that the use of seat belts is associated with higher fatality rates than not using seat belts.O B. The results suggest that the use of seat belts is associated with lower fatality rates than not using seat belts.O C. The results suggest that the use of seat belts is associated with the same fatality rates as not using seat belts.O D. The results are inconclusive. A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2949 occupants not wearing seat belts, 28 were killed. Among 7899 occupants wearing seatbelts, 20 were killed. Use a 0.01 significance level to test the claim that seat belts are effective in reducing fatalities.

A student pursuing a degree in English as a second language believes the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. To test her claim she randomly selects 313 female factory workers and out of them 48 could not speak English. She then randomly selects 400 male factory workers and out of them 43 could not speak English. Test her claim at a=0.05 to see if she was right. The correct hypotheses are: O Ho:PF Рм (сclaim) O Ho:PF 2 PM HA:PF < PM(claim) O Ho:PF = pM HA:PF + PM(claim) Since the level of significance is 0.10 the critical value is -1.282 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak…
ALREADY HAVE FIRST THREE ANSWERS NEED THE REST. ANOVA. Dr. Milgram is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: 4 df Within-Group: 9 df Between-Groups: 2 Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22)…
