Nowadd the last two digits of your roll number with every value of Z and name the new variableas Y. For example, if your roll number is 2652 then add 52 with every value of Z and namethem Y, that is Y = Z+ 52. Thus, you will have a New Data Set of 50 X values and 50 Yvalues. Now, do the following for your New Data Set:1. Construct a frequency distribution for Y taking suitable class-intervals and followingthe exclusive method.2. Find the Mean and Standard deviation of Y and comment on the results.3. Construct the regression equation considering X as independent variable and Y asdependent variable. And, comment on the use of this equation. Data Table:SerialXZSerialXZSerialXZ122183735227419823649.36.5206.37514472192387256.822323981

Problem 2: Supplement for Weightlifting Continued In comparison to the previous problem, let us say that the weightlifting supplement company informed you that how long a female weightlifter has been lifting impacts the amount of muscle mass they can gain. Suppose that you changed your data collection method from what you did in Problem 1. Now you randomly select one weightlifter from each group (supplement and placebo) that have been lifting for 39 to 40 months. Next, you randomly sample one weightlifter from each group that have been lifting for 37 to 38 months. Then, you continue this process until the 20th pair of weightlifters have lifted for 2 months or less. The data contains the whole body lean mass difference in pounds and training experience in months. Can you infer that the supplement group gained more muscle mass on average than the placebo group? Use a = 0.05 for any hypothesis test. List the conditions necessary to complete this probiem. g) Calculate the test statistic…
