Hello, I need help with these 3 problems, they are from a math lab and the professor ask me to use "Statdisk Online" but I really don't know how to do these problems, but I already did problem 7.1 and 7.5 and the professor asks me for at least one screenshot per question of the Statdisk Online page. Here I attach a link with the laboratory manual, the chapter goes from page 51 - 59, but the questions are on page 59. Please help me as much as you can, I really don't understand much how to use Statdisk to solve these problems.

CHAPTER 7 WORKBOOK: Confidence Intervals and Sample Sizes In 7-2, use Statdisk with the sample data and confidence level to construct the confidence interval estimate of the population proportion p. 7-2 From a 3M Privacy Filters poll in which respondents were asked to identify their favorite seat when they fly: n = 806, x = 492 who chose the window seat. Use a 99% confidence level. 7-3 Pulse Rates A physician wants to develop criteria for determining whether a patient's pulse rate is atypical, and she wants to determine whether there are significant differences between males and females . Use the sample pulse rates from Elementary Statistics 14th edition, Data Set 1 "Body Data" (GENDER: 1 = male, 0 = female). a. Construct a 95% confidence interval estimate of the mean pulse rate for males. b. Construct a 95% confidence interval estimate of the mean pulse rate for females. c. Compare the preceding results. Can we conclude that the population means for males and females are different? Why or why not? 7-4 Sample Size for Proportion You have been hired by the Ford Motor Company to do market research, and you must estimate the percentage of households in which a vehicle is owned. How many households must you survey if you want to be 94% confident that your sample percentage has a margin of error of three percentage points? a. Assume that a previous study suggested that vehicles are owned in 86% of households. b. Assume that there is no available information that can be used to estimate the percentage of households in which a vehicle is owned
