Question

do for ONE model please.

1. One of the costly items in a production plant is the amount of water used by the facilities each month. An engineer decided to investigate water usage by collecting seventeen observations for seventeen months on his plant's water usage and other variables. he decided on the following variables Temp-average monthly ambient temperature (F) Production amount of Days number of days of plant operation in the month Persons-number of persons on the monthly payroll Water monthly water usage (gallons) Complete the five regression models described below. Complete the table of"r" values and supply the fit equations. production (106 lbs) a. b. Discuss the fits. Which fit appears best and worst based on the "" values. c. Plot the data and fit results from modelin four plots. In each plot, the water usage is plotted versus one of the four independent variables. Discuss your results. Comment on the nature of the problem. Consider if the variables are appropriate. Should other variables be considered?
