You have acquired property south of Winnipeg that fronts on the Red River, a river that hasa history of flooding its banks during spring runoff. Historical records show that flood crestlevels are normally distributed. On average, the river has reached a height of 5 metres aboveits normal level with a standard deviation of 2 metres. The main floor of your home sits 7metres above normal river level.Should you be arranging to have a berm built around your home and if so how high shouldthe berm be? In answering this question, assume that you want to be sure that 99% of thetime, spring flood water will not reach your home.

Let a random variable X denotes the flood crest level. Then, X has normal distribution with mean μ=5…

Jack's clothing sells on average, 25 shirts per week, sometimes a little more, sometimes a little less but typically a deviation of about 3. The cost per jacket is $65. Because Jack's is located in a sketchy part of town their insurance on inventory is 33% on all goods. The good news is free shipping to customers although UPS charges Jack's $8.50 for every delivery. It takes 2 weeks from the time jackets are ordered until they are received. Jack's supplier has said they only ship by pallet, and each pallet contains 75 jackets. If the reorder point is 50 what is the average flow time?

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.1% of the thermometers are rejected because they have readings that are too high and another 2.1% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others.
