Весаиse Excel makes emors b. Because when going to a range table from an exact-value table or distribution, the values become approximate c. Because the spreadsheet calculates the values in different ways d. Because the variance is calculated differently If you were to convert the frequency table on the bottom of the previous page to a percentage/probability table, which would be the correct values: a. A= 25.00%, B = 30.00%, C = 22.00%, D = 15.00%, F = 10.00% b. A= 28.22%, B= 21.85%, C = 16.81%, D = 16.81%, F = 12.66% c. A=17.40%, B= 22.35%, C = 35.28%, D = 17.53%, F = 14.85% d. A= 30.43%, B = 21.74%, C = 17.39%, D = 17.39%, F = 13.04% e. A= 35.27%, B = 22.91%, C = 18.56%, D = 18.56%, F = 11.36%
