House values in Martin, TN are known to have a distribution that is skewed to the right instead of being normally distributed. Assume that house values in Martin, TN have a mean of $64,500 with a standard deviation of $21,350. Answer the following probability questions concerning house values in Martin, TN. Part 1: If 1 randomly selected house in Martin, TN is selected, what is the probability that this house has a value under $60,000? Part 2: If 30 randomly selected houses in Martin, TN are selected, use the Central Limit Theorem to determine the probability that their average value is under $60,000?

Mariah Jacobsen is the marketing manager at ABC Electronics, a major consumer electronics supplier in the northwest. Over the last five years, sales of the company's flagship product - the Wizer Anonymizer (the WA) - have been 45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so. Ms. Jacobsen believes that the distribution of the WA's sales is normal with a standard deviation of 1500 units. If she were asked to make a forecast of next year's sales to upper management, what is the likelihood that she would be correct if she predicts sales between 43000 and 46000?
