Autorama Case
Third assignment
1. A little peek at the Autorama Consider the 80.5 expected car buyer in the $45,000–$55,000 income group from the Autorama case. Using the same assumptions we made for the case, determine the expected number of sales in each price bracket from this group. Hint: Use the normal distribution to determine the probability that someone in this group would buy a car in each price bracket. You may wish to do your calculations in a spreadsheet. 2. Shore Realty Shore Realty sells real estate in Oklahoma. The company would like to be able to predict the selling price of new homes based on the home’s size. It has collected data on size (“sqfoot” in square feet) and selling price (“price” in dollars), which are stored in the file shore.xls. Use the data in that file to answer the following questions: • Use Kstat or Excel to construct a scatterplot for these data with size on the horizontal axis. • Use Kstat to dtermine the estimated regression equation. • Predict the selling price for a home with 2,600 square feet. 3. Accesss bschools2002.xls which contains data regarding the top 30 business schools based on the 2002 Business Week ratings. Many business schools surveys including this one report mean base salaries and median base salaries. These two statistics tend to be similar. KStat can help us find a relationship between the two for this dataset. (a) Use KStat to construct a scatterplot with mean base salary on the vertical axis and median base salary on the horizontal axis. (b) Does the relationship appear linear? (c) Use KStat to perform a regression of mean base salary vs. median base salary. Write out the estimated regression line. (d) Use your regression equation to estimate themean base slary for a school with a median base salary of $77,000. (e) Use your regression equation to estimate the mean base salary for a school with a median base salary of $88,000.

    A manager at AJ Davis department store has speculated on certain customer statistics in hopes to get a better understanding of his target market, thus improving revenue though marketing and sales initiatives. His first assumption is that the average annual income of 50 randomly selected customers is less than $50,000. After calculating the data this assumption proved to be true, as we can say with 95% certainty that the income is less than $47,510. The next assumption is that more than 40% of his customers live in urban areas. After computing the data, we cannot be certain this is accurate. The data falls too close for me to be confident in this assumption; the 95% confidence interval is too wide. The third assumption is that the average number of years the customers have lived at their current home is less than 13 years. Again, this was an accurate assumption as we can say with a high degree of confidence than most customers have lived at their current location for less than 13 years as the mean was found to be 12.38 years. Finally, the manager assumed the average mean credit balance for suburban customers is greater than $4300. This was found to be an accurate assumption. The 95% lower confidence limit was found to be greater than $4300.…

    2) Problem 11: You are the manager of a midsized company that assembles personal computers. You purchase most components-such as random access memory (RAM) – in a competitive market.
