Please show all work so I learn how to do it!

ssume that you are managing a warehouse that utilizes a manual process to unload truckloads hat arrive at your facility. You figure the average time to unload a truck is 65 minutes with a tandard deviation equal 50.|Use this data to answer the following questions. The following four questions require you to calculate probabilities given z-scores (i.e., the number of standard deviations from the mean). (2 points each) 1. What is the probability that the unloading time is 2 standard deviations below the mean or less? [ Hint: P(z2.0)=?] 2. What is the probability that the unloading time is 3 standard deviations above the mean or more? 3. What is the probability that the unloading time falls between 2.0 standard deviations below the mean and 3.0 standard deviations above the mean? [Hint: P(2.023.0)= ?] 4. What is the probability that the unloading time is within two standard deviations of the mean. [Hint: P(2z2)= ?] 5. What is the probability that the unloading time is greater than the mean? { Hint: P(z0)
