here is my question

2. Provide a printout in which you find the Statistics Here . Descriptive . mean and standard deviation for the 75. Variable - N Mean SD sizes/mileages of your data set. Also, list Size - 75 - 576. 41 93. 272~ your size/mileage for your 10" and your 40th observation below. For all of question 2, treat these values . as the mean and. standard deviation of the population when answering questions. Size/Mileage for Observation #10: 598- Size/Mileage for Observation #40: 509 a.-For this problem, assume that the distribution for all sizes/mileages in the population are normally distributed (may not really be true). Find the proportion of all sizes/mileages that would fall between the sizes/mileages of your 10" and 40" observations. To receive full credit, you should include pictures of the normal curve (labeled with both x and.z- values) with the pertinent probabilities shaded in the picture. - 20 b.-Assuming the distribution of the sizes/mileages are normal, use the mean and standard deviation you found above to locate the 97.5" percentile in the size/mileage distribution. To receive full credit, you show as much work as possible.~ c. Suppose you take a future sample of 100 sizes/mileages . from your population. Describe the sampling distribution for the x-bar value that you would find. (hint: there should be three parts to this answer) d. Use the sampling distribution to find the probability that the sample mean from that future. sample would exceed the size/mileage for Observation #40. .To receive full credit, you. should include pictures of the normal curve (labeled with both x-bar and z-values) with the pertinent probabilities shaded in the picture.~
