The table below shows the weights of seven subjects before and after following a particular diet for two months. Subject / A / B / C / D / E / F / G ////////////////////////////////////////////////// Before / 165 / 151 / 196 / 175 / 179 / 172 / 191 ////////////////////////////////////////////////// After / 166 / 154 / 169 / 164 / 176 / 193 / 169 Using a 0.01 level of significance, test the claim that the diet is effective in reducing weight. Use the critical value method of hypothesis testing.

Demand for walnut fudge ice cream at the Sweet Cream Dairy can be approximated by a normal distribution with a mean of 21 gallons per week and a standard deviation of 3.5 gallons per week.

The new manager desires a service level of 98 percent. Lead time is two days, and the dairy is open seven days a week. If an ROP model is used, what ROP would be consistent with the desired service level? ( Hint: Work in terms of weeks.)

Periodic Inventory Using FIFO, LIFO, and Weighted Average Cost Methods

The units of an item available for sale during the year were as follows:

There are 17 units of the item in the physical inventory at December 31. The periodic inventory system is used. Determine the inventory cost using (a) the first-in, first-out (FIFO) method; (b) the last-in, first-out (LIFO) method; and (c) the weighted average cost method (round per unit cost to two decimal places and your final answer to the nearest whole dollar).
