The table below gives the summary statistics for the weekly payroll of a small company. a) Suppose business has been good and the company gives every employee a $50 raise. Find the new summary statistics and report the new values below. (HINT: You do not need the data to answer this question. Think about what the distribution looks like, and what would happen to the center and spread if all the data values became 50 larger.) Use the following two sample data sets to answer the questions below. a) Calculate the sample means of both data sets. potasetA=1,4,7,8,500.DatasetB=1+4+7+8+500,5=490+493=49518. =1+4+7+1=520/5=104 b) Without doing any further calculations, which data set do you think has the larger sample standard deviation, and why? c) The sample standard deviation of Data set A is 221.39. Check your answer from the previous part by calculating the sample standard deviation of Data Set B. Comment on the results
