An investigator wants to test the effectiveness of visualization on sports performance. she randomly assigns participants to two groups. participants in the visualization group imagine themselves swinging a golf club perfectly for 20 minutes prior to a session on the driving range. participants in the control group read golf magazine for 20 minutes prior to a session on the driving range. all participants do this procedure each day for five days. the dependent measure, the average flight distance of the ball, is calculated for each participant after each session. this is an example of a design.

Jimmy's delicatessen sells large tins of tom tucker's toffee. the deli uses a periodic review system, checking inventory levels every 88 days, at which time an order is placed for more tins. order lead time is 22 days. daily demand is a constant 1515 tins, so average demand during the reorder period and order lead time (1010 days) is 150150 tins. draw a sawtooth diagram. assume that the beginning inventory level is equal to the restocking level and the desired service level is 99.9%. what is the safety stock level? (hint: look at the formula for calculating restocking level.) what is the average inventory level? the safety stock level is average inventory level is __chart: time (10,20,30), tins (0,150) lines touching both axisthe safety stock level is 0 tinsthe average inventory level is 75 tins
