Develop a multiple-regression model for auto sales as a function of population and household income for 10 metropolitan areas.

Estimate values for b₀, b₁, and b₂ for this model:
AS = b₀ + b₁ (INC) + b₂ (POP)
Are the signs you find for the coefficients consistent with your expectations? Explain.
What percentage of variation in AS is explained by this model?
What point estimate of AS would you make for a city where INC=23,175 and POP=128.7?

A study of the population average income in a certain area was conducted. A sample of 25 households was selected at random for a poll. The sample based average annual income was found as (X-bar) = $53,600, with the sample standard deviation found as (S = $12,000). Assume that individual records are normally distributed with an unknown population standard deviation. Estimate the population average income with the 99% confidence. Answer all questions below.
