- Can you guys help me on this? Thank you!The grade of OMG 321 was normally distributed with a mean of 81 and a standard deviation of 3. (round z value to the second decimal and probability to the fourth decimal place)Jillian Michaels and Bob Harper are all- time famous American trainers. Michaels thinks that her clients lose more weight on average than the clients of Harper. Harper naturally disagrees with Michaels. In order to settle the dispute, the two trainers agree to each work with 15 different clients for six months. The table below summarizes the weight loss (Ibs) of each group: J. В. Michaels Harper Mean 25 21 SD 5.1 2.5 Size 15 15 1. Assume normality in the population distribution, construct a 90% confidence interval for the population difference of the mean weight loss using the critical value of 1.76 (Note: all values are given, no R codes needed) 2. What does it mean to be at "90% confident"? Would the 95% confidence interval be wider or narrower? Would the margin of error be wider or narrower? (Note: no calculation is needed) 3. According to the confidence interval you found in part (a), what can be concluded about Michaels' claim? (Note: you do NOT need to do the 5-step significance…

Grades will be assigned according to the follwing rule: the top receives A's, the next 20% receive B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's. Some may refer to this as "curving" The 40 grades were as follows: 30, 53, 88, 69, 77, 57, 58, 43, 63, 51, 69, 88, 86, 84, 50, 83, 91, 76, 57, 90, 45, 79, 41, 80, 62, 66, 71, 58, 92, 85, 57, 74, 63, 60, 99, 85, 70, 93, 67, 53 Do you think ths method of grading is fair to all students? Explain your answer 2. Under what circumstances would some students NOT like this method of grading? 3.
