You know that the average college student eats 0.75 pounds of food at lunch. If the standard deviation is 0.2 pounds of food, th
Fynjy0 [20]

Answer: $53.95

Step-by-step explanation:

Given: \mu=0.75 pounds

\sigma= 0.2 pounds

n= 50

Two tailed critical z-value for 90% confidence level = 1.645

Let x be the total amount of food that a cafeteria should have on hand to be 90 percent confident that it will not run out of food .

z-score = \dfrac{x-\mu}{\sigma} =\dfrac{x-0.75}{0.2}

Then, \dfrac{x-0.75}{0.2}=1.645

x-0.75=1.645\times0.2\\\\\Riightarrow\ x-0.75=0.329\\\\\Rightarrow\ x= 0.329+0.75\\\\\Rightarrow\ x= 1.079

Foe 50 students, total amount of food = 1.079 x 50 = $53.95

hence, the cafeteria should have food of amount $53.95 so that it is be 90 percent confident that it will not run out of food.
