i want you $to$ write the answer after i ive you all the info and exaplin your answer. $To$ earn full credit, use the following two$-$step process $to$ answer each $of$ the following questions. Step $1$: Draw the standard normal curve, draw lines that indicate the relevant upper $an\frac{d}{o}r$ lower boundaries under the curve, label the $z-$ and $x-$value $(when$ appropriate$)$ for each boundary, and shade $in$ the relevant area under the curve. Step $2$: Show all computational work and draw a box around the final answer.Example: Assume that a sample $of$ test scores are normally distributed with a mean $of82$ and a standard deviation $of4.$ Find the probability that a single test score falls between $74$ and $78.$ Assume that you are managing a warehouse that utilizes a manual process $to$ unload truckloads that arrive $at$ your facility. Assume the average time $to$ unload a truck $is70$ minutes. Also assume the standard deviation $(s)is13$ and $6.$What $is$ the probability that unloading time takes less than $70$ minutes? $[Hint$: $P(x70\mathrm{.}0)=?]$
