Question 4(13 marks = 2 + 2 + 2 + 2 + 2 + 2 + 1)An event organiser would like to predict the number of portaloo lavatories required for outdoor entertainment events based on the volume of food to be consumed at the event. The organiser has collected the following data.Number of lavatories Volume of food consumed (Kg)17 125121 87593 72317 15466 46948 350119 1156108 100067 50081 683104 72328 25665 523a. Plot a scatter diagram for this data. Describe (briefly) the relationship between the volume of food consumed and number of portaloos.b. Assuming a linear relationship, calculate the regression equation for this data. Please show your calculations or insert your summary output from Excel.c. Interpret the estimatedY intercept, , and the estimated slope, .d. Perform residual analyses and determine whether the sample data meet the regression assumptions of equal variance (homoscedasticity) and normality.e. Is the amount of food consumed a statistically significant predictor of portaloos? Please explain your answer.f. Comment on the goodness of fit of this model.g. Predict the number of lavatories if event attendance is 50,000.
