The file medinc.mtw contains data on the median incomes (medinc)of census dissemination areas in Toronto. (a) Treating this set ofdata as the population, use Minitab to calculate the populationmean and the population standard deviation for the medinc variable.Set aside all population information until parts (d) and (e). (b)Use Minitab (Calc Menu – Random Data – Sample from Columns) to drawtwenty samples of size n = 40 from the Toronto medinc population.This procedure must be replicated twenty times (note that if youopen up the same sampling dialog box each time from the menu, thenyou only have to replace the last destination column with the nextone. In Minitab Express, you must specify the sample size each timebut you do not need to specify the destination column). For eachsample, use Minitab to calculate the sample mean. Note that whenyou can use the Descriptive Statistics function, you can specifythe calculation of only the sample means of all your samples atonce. (c) Copy the sample means into a new column and calculate themean and standard deviation of your sample means. (d) The samplingdistribution of the sample mean has an average equal to thepopulation mean. Explain why the mean in part (c) may be differentfrom the population mean in part (a). (e) How would you use thesample standard deviation in part (c) to estimate the populationstandard deviation in part (a)? How close is your estimate to thetrue value? I am only looking for how we calculate e) I have allthe others done and my sample standard deviation is 1593.5 with amean of 25251.7. I'm using n=40 and perhaps that is where I amgoing wrong
