Hello, could you please help me with these 2 problems. I have to solve them in "Statdisk Online," provide a written answer and a screenshot of the entire Statdisk Online page as evidence that I use this particular page, the problem is that I don't know how to use this page very well so I really need your help with the screenshot. Here I will attach the corresponding chapter, perhaps it will serve as a context.

Chapter 9: Inferences from Two Samples CHAPTER 9 WORKBOOK: Inferences from Two Samples 91 92 Are Seat Belts Effective? A simple random sample of frontseat occupants involved in car crashes is obtained. Among 2823 occupants not wearing seatbelts, 31 were killed. Among T765 occupants wearing seatbelts. 16 were killed (based on data from "Who Wants Airbags?" by Mever and Finney, Chance, Vol. 18. No. 2]. Construct a 90% condence interval estimate of the difference between the fatalityr rates for those not wearing seat belts and those wearing seat belts. What does the result suggest about the effectiveness of seat belts? Fast Food Refer to Elementary Statistics 1-51'h Edition, Data Set 35 "Fast Food." Use a 0.05 significance level to test the claim that the sample of drive through service times for McDonald's dinner and Burger King dinner are from populations with the same mean. If there is a statistically significant difference, does that difference have practical significance? {Assume that the two samples are independent simple random samples selected from normallv distributed populations. Do not assume that the population standard deviations are equal.) Test statistic: Critical value{s]: Pvalue: Conclusion
