Use the modified Levene test to determine if the assumption of equal variances is satisfied in Problem 3.27: Brand Life 1 1 100 2 1 96 3 1 92 4 1 96 5 1 92 6 2 76 7 2 80 8 2 75 9 2 84 10 2 82 11 3 108 12 3 100 13 3 96 14 3 98 15 3 100 Use alpha = 0.01. Did you reach the same conclusion regarding the equality of variances by examining residual plots?

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
