- Suppose you are assigned the number 1, and the other students in your statistics class call out consecuuve Rul (a) Explain how you could get a random sample of four students from your statistics class. (Select all that apply.) B Randomly choose four of the first students that walk into the classroom. 0 Randomly choose four of the students that are sitting in the back row Randomly choose four of the last students that walk into the classroom Randomly choose four of the tallest students in the classroom g Use a computer or random-number table to randomly select four students after numbers are assigned. b) Explain why the first four students walking into the classroom would not necessarily form a random sample. (Select all that apply perhaps they are students that had a class immediately prior to this one. ) Perhaps they are students with lots of free time and nothing else to do. u Perhaps they are excellent students who make a special effort to get to class early.

Jimmy, a junior researcher in the team, has randomly selected a sample of 25 male runnersfrom a high school and the time (in seconds) for each of them to complete a 400-meter race was recorded.The sample mean running time was 53 seconds. It is assumed that the running time in a 400-meter racefollows a normal distribution with a population standard deviation of 5.5 seconds.(a) Give a point estimate of the population mean running time for a 400-meter race.(b) Calculate the sampling error at 95% confidence level.(c) Construct a 95% confidence interval estimate of the population mean running time for a 400-meter race. (d) If instead of 25, 80 male runners are selected for the study, what is the sampling error at 95% confidencelevel? When the 95% confidence interval is constructed based on a sample with 80 male runners, wouldyou expect the interval will be (I)…The numbers 1, 2, 3 and 4 are written separately on four slips of pane- The slips are put in a box and mixed thoroughly.

- As part of a statistics project, a teacher brings a bag of marbles containing 700 white marbles and 300 red marbles. She asks her students to determine how many red marbles are in the bag without counting them.A student randomly draws 100 marbles from the bag. Of the 100 marbles, 33 are red.The target population consists of The 100 marbles drawn by the student The 1000 marbles in the bag None of the above The 33 red marbles drawn by the student The 300 red marbles in the bag The sample consists of The 1000 marbles in the bag The 100 marbles drawn by the student The 33 red marbles drawn by the student None of the above The 300 red marbles in the bag Based on the sample, the student would estimate that ------ marbles in the bag were red.Two women are going to give birth to one child each.
