Anestetic [448]

Answer: 0.086

Explanation: There are 1,000 milliliter in a liter. Since 86 is below 1,000, your answer won’t be in front of the decimal. For example, if you had 3,000 milliliters, your answer would be 3.0 liters.

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.
