Question 38 (5 points) Saved Regression analysis was performed on a time series containing 4 years of quarterly sales. The sales data contains a seasonal effect, but no trend. The following estimated regression equation was obtained. P- 112.0-16.0 Ofr2 + 26.0 Ofr3 + 10.0 Or4 The sales forecasts for Quarters 2 and 4 of Year 5 are a) 112, 96 b) 96, 132 9 132, 116 O d) 96, 1221. carefully study of the deceased Alzheimer patients has revealed that in most cases, they contain tangles of amyloid beta protein, a substance not found in similar concentration in normal brains. Research evidence (Yanker et al., 1990) suggests that this substance causes damage to neurons that project from nuclei in the basal forebrain to the hippocampus and cerebral cortex (Coyle, 1987). 2. An entirely different kind of antidepressant is lithium. It is usually administered as lithium chloride. This drug has been found to be quite effective in treating people with bipolar disorder and is successful within 60 to 70 percent of these persons (Julien, 1995). Lithium us generally administered along with antipsychotic and or antidepressant medications. Unfortunately, lithium has serious side effects -- excessive doses can cause delirium and even death. 3. Barbiturates are drugs that act as depressants, reducing activity in the nervous system and behavior output. It is contained in sleeping pills and relaxants, constitute a second type of depressant. Benzodiazepines is a drug used for anxiety disorder. In this group there are Valium, Ativan, Xanax and Librium. It is a minor tranquilizer. It is safer than barbiturates. It is less addicting.Problem 10-27 (Algorithmic] A perishable dairy product is ordered daily at a particular supermarket. The product, which costs $1.23 per unit, sells for $1, 74 per unit. If units are unsold at the and of the day, the supplier takes them back at a rebate of $1 per unit, assume that daily demand is approdmately normally distributed with a = 145 and c - 25, Wore: Lise Appendix B In Identify the areas for the standard normal distribution, a. What is your recommended daily under quantity for the supermarket? Round your answer to the nearest whole number. b. What is the probability that the supermarket will sell all the units it orders? Round your answer to three decimal places. P( Stockout) = 0.3177 c. In problems such as these, why would the supplier offer a rebate as high as $ 17 For example, why not offer a nominal rebate of, say, 25c per unit? What happens to the supermarket order quantity as the rebate is reduced? The higher rebate decreases the quantity that the supermarket should order. L sample(1:6,10,replace=TRUE) B. Create a table and a barplot with this list. Enter: > tabletL) > barplot[table{L)} Question: What is the (empirical) probability of getting a \"five\" according to your table? C. Repeat part A and B above by simulating 100 rolls and based on these simulations calculate the (empirical) probability of getting a \"five". D. Repeat part A and E for 1,000 and 10,000 simulations. Report how far is the (empirical) probability of getting a \"five\" based on your 10,000 simulations from the theoretical probability (which equals 1/6)
