Iris Sanchez Objective: find the standard deviation and quantities used to calculate the standard dev Help me solve this | 4 parts remaining The data shows the total number of employee medical leave days taken for on-the-job accidents in the first six months of the year: 20, 11, 28, The data shows the total number of : 12, 29, 20. _ Find the standard deviation. The standard deviation is about Deviation x Deviation Type an integer or decimal rounded 20 (0)(0) = 0 11 (-9)(-9)= 81 28 (8)(8) = 64 12 (- 8)( -8) = 64 29 (9)(9) = 81 20 (0)0) = 0 Now find the variance by dividing the sum of the squared deviations by 1 less than the number of values in the data set. Variance sum of squared deviations 0 +81 +64+ 64 +81 +0 Find n - 1 and simplify. Textbook Print Clear all Check answer Help me solve this View all
