Question 3 Management of a soft drink bottling company has the business objective of developing a method for allocating delivery costs to customers. Although one cost clearly relates to travel time within a particular route, another variable cost reflects the time required to unload the cases of soft drink at the delivery point. To begin, management decided to develop a regression model to predict delivery time based on the number of cases delivered. A sample of 7 deliveries within a teritory was selected. The delivery times and the number of cases delivered were organized in the following table: Customer No. of Cases Delivery Time 1 14 24 16 31 3 17 28 4 19 30 11 20 6. 16 22 7 24 40 a) Use the least-squares method to compute the regression coefficients. b) Write down the estimated equation and interpret the meaning of the coefficients in this problem c) Predict the mean delivery time for 26 cases of soft drink. d) Determine the value of the extent of relationship between delivery time and number of cases and interpret your result. e) Determine the coefficient of determination and explain its meaning in this problem. f) What variation in delivery time is not attributed to the number of cases g) At the 5% significance level, determine whether there a correlation between delivery time and number of cases.

Question1 The number of grams of carbohydrates contained in 1-ounce servings of randomly selected chocolate and nonchocolate candy is listed here. Is there sufficient evidence to conclude that the difference in the means is significant? Use a = 0.01. Chocolate: 29 25 17 36 41 25 32 29 38 34 24 27 29 Nonchocolate: 41 41 37 29 30 38 39 10 29 55 29 Question 2 In Cleveland, a sample of 73 mail carriers showed that 10 had been bitten by an animal during one week. In Philadelphia, in a sample of 80 mail carriers, 16 had received animal bites. Is there a significant difference in the proportions at 1% significance level?
