a sample of restraunts in a city showed that the average cost of a glass of iced tea is $1.25 with a standard deviation of 7 cents. if a new restraunt charges a price for iced tea that has a z value of 1.25, then what is the teas actual cost

1 answer

z = (x-mean)/sigma
so
x = mean + z*sigma

1.25*7 = 8.75 cents

1.25 + .0875 = $1.34
