# Weekly fast food expenditures by young adults are normally distributed with a mean of \$44.65 and a standard deviation of \$14.

Weekly fast food expenditures by young adults are normally distributed with a mean of \$44.65 and a standard deviation of \$14.25.

A. What is the probability that the average weekly amount spent on fast food by a random sample of 11 young adults will be between \$35.00 and \$40.00? round to 4 places after the decimal point.

B. Young adults in the bottom 4% of weekly expenditures on fast food are designated as FFF (fast food fit). What money amount represents the maximum weekly expenditures for FFF young adults? round to 2 places after the decimal point.

C. What is the probability that a randomly selected young adult will spend more than \$48 weekly on fast food? round to 4 places after the decimal point.

Question A. Z= (\$40.00 - \$44.65)/\$14.25 - (\$35.00 - \$44.65)/\$14.25 P = (z=-0.33) - (z= -0.68) P =... View the full answer
