23 23 25 26 28 28 Consider the sample data shown in the table above. We will build a table to find the sample standard deviation, 5. a. First, we need to find the sample mean (round to one decimal}: :E = 25.5 J 0' Part 2 of 4 Next, we fill in the deviations column. 23 23 25 26 28 28 Do this on a separate sheet of paper. Then enter the deviation of the value a: = 23. Keep the sign if it's negative. b.When:r 2 23,3 :E = C] c. Based on your table, what is Z (a: 5:)? C] d. Without any rounding, what value would you expect for Z (:1: it)? C]
