For the general population, the mean on this test is 100. Below are the scores on this test for the applicants. 139 118 108 102 121 112 99 101 117 23 Click here for the Excel Data File The president is interested in the overall quality of the job applicants based on this test. a. Compute the mean and the median scores for the 10 applicants. (Round your answers to 1 decimal place.) Mean Median

also, what would you report to the president? applicants are better or not better that regular people.

Answer 1

(page 1) scores of 10 people are 139,118,108,102,121,112,99 ,101,117,23. mean of the score is = Exi = (139+ 118 +108 +102 +21+112 +99+101+117+23) 10 1040 = 104 [mean = x= 1067 Now, we have to find median of the score, ascending order of the given score, 23,99, 101, 102,108,112,117,118,121,139 middle observation are 108 and 112 Because number observation is even, .. median - 108 +112 = 10 3 2 median = 110 median is the middle value in a rank ordered sequence, and average is the sum of all Observation values divided by the number of observation, medions are not affected by outliers, but averages can swing wildly due to extreme anomalies that are not relevant to the norm, median is better than mean
