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?
Please answer B, C, & D.
A bottle of water is advertised as containing 1 liter of water. However, after testing a few hundred bottles, you find the average amount of water is normally distributed and contains 1.07 liters on average with a standard deviation of 0.05.

Manny creates a new type of bowling ball. His new model knocked down an average of 8.96 pins, with a standard deviation of 1.35 pins. The older model bowling ball knocked down 7.79 pins on average, with a standard deviation of 3.63 pins. He tested each bowling ball model 10 times. What is the effect size of the difference in the bowling ball models? (Write your answer below, to two decimal places as a positive value; sign doesn't matter)
