a) Use the output shown above and write an equation that can be used to predict the monthly sales. b) Interpret the coefficients of the estimated regression equation found in Part a. c) What can you say about the strength of this relationship? d) Carry out a test of whether Xi and Y are significantly related. Use a .05 level of significance. e) Carry out a test of whether Xzand Y is significantly related. Use a .05 level of significance. Problem 5.) For a company below are monthly data on the transportation cost of its operations. This cost comes as a result of mining volumes, fuel charges and local road taxes in each month. These three variables more or less decide the total transportation cost the company incurs.

Mining Volumes: Fuel Charges: h) What can you say about the strength of this relationship i) Use a .05 level of significance, to explain which independent variable are significant and why. Problem 6) SHORT ANSWER. Write the word or phrase that best completes each state- ment or answers the question. 1) The athletic departments at 10 randomly selected U.S. universities were asked by the Equal Employment Opportunity Commission to state what percentage of their nursing scholarships were presently held by women. The responses were 5, 4, 2, 1, 1, 2, 10, 5, 5, 5. Find the mean, median, mode, and geometric mean. Which is the most appropriate measure of central tendency? The least appropriate? Explain your an- swer. Is there an outlier?
