Let "X=" the number of ounces of soda: "X\\sim N(\\mu, \\sigma^2)"
Then
Given that "\\mu=12 \\ ounces , \\sigma=2\\ ounces"
"=1-P(Z\\leq -1)\\approx1-0.158655\\approx0.8413"
The probability that a randomly selected customer takes over 10 ounces of soda is "0.8413"
"=P(Z< 1)-P(Z<0.5)\\approx0.841348-0.691462\\approx"
"\\approx0.1499"
The probability that a randomly selected customer takes between 13 to 14 ounces of soda is "0.1499"
Given that "n=100"
"\\approx0.8849"
"0.8849\\cdot100=88.49\\approx88"
88 of the next 100 customers will take an average of less than 12.24 ounces.
