A certain newspaper provides the net asset value, the year-to-date percent return, and the three-year percent.return for 882.mutual funds at the end of 2017. Assume that a simple random sample of 12 of the 882 mutual funds will be selected for a follow-up study on the size and performance of mutual funds. Use the ninth column of the table of random numbers, beginning with 13554, to select the simple random sample of 12 mutual funds. Begin with mutual fund 554 and use the last three digits in each row of column 9 for your selection process. What are the numbers of the 12 mutual funds in the simple random sample? (Enter your answers as a comma-separated list.)

2. We wish to analyze the monthly water usage of a production plant, Y (in gallons), with respect to its monthly production X₁ (in tons), mean monthly temperature X₂ (in °F) and the monthly number of days X3 of plant operation using the data given in the file 'WATER.xlsx'. The following models are considered: I: II: Y = Y = Bo + B₁X₁ + B₂X2 + ß3X3 + E, Bo + B₁X₁ + B2X2 + B3X3 + B₁X1X2 + B5X₁X3 + B6X2X3 + ε Perform your tests at a = 10% in this question. (a) Generate a matrix scatter plot and state the relationship among these variables. (b) Use R/Minitab to estimate the parameters of Model I, set up three hypotheses to test whether each variable is useful given that the other variables are in the model. (c) In Model II, the interaction terms among these three variables are considered. Using the sum of squared residuals from the estimates of models I and II, do an F-test to test the whether all these interaction terms are useful jointly in predicting the monthly water usage of the…
