A real estate investor wants to decide whether it is a good investment to build a high-end shopping complex in a given suburb of Melbourne. His main concern is the total market value of the 3,605 houses in the suburb. He commissioned a statistical consulting group to take a random sample of 200 houses and the consulting group obtained a sample average market price of $985,000 and a sample standard deviation of $25,800. i. Provide a point estimate of the market price of the houses in the given suburb. Explain your reasoning. ii. Construct a 90% confidence interval estimate for the true average market price of the houses in the given suburb and provide a plain language interpretation of the interval.
