This table gives further details of the multiple regression estimated in Exercise 31. Assume that the MRM satisfies the conditions for using this model for inference.
(a) Fill in the t-statistics.
(b) Estimate the p-values using the Empirical Rule. Only rough estimates are needed.
(c) Does the addition of Distance to a simple regression using only population as an explanatory variable produce a statistically significant increase in R2?
(d) If the population of a city were to grow by 10,000, on average what effect would this growth have on revenue? Give a range, rounded to presentation precision.
