Question

Weekly demand for milk at a small grocery store is normally distributed with a mean of 251 gallons per week and standard deviation of 33 gallons per week. a. With 93% probability, the store should expect to sell at least how many gallons of milk per week?

Answer 1

Answer: SolutionGivenmean = 251standard deviation = 33(a)Hence, X = 300

Explanation:

Answer 2

Given

mean = 251

standard deviation = 33

(a)

`\begin{gathered} P(Z<(X-251)/(33))=0.93 \\ \\ \Rightarrow(X-251)/(33)=1.47579 \\ \\ \Rightarrow X-251=48.70107 \\ \\ \Rightarrow X=300 \end{gathered}`

Hence, X = 300
