The mean selling price of senior condominiums in Green Valley over a year was $215,000. The population standard deviation was $25,000. A random sample of 100 new unit sales was obtained. a. What is the probability that the sample mean selling price was more than $210,000? b. What is the probability that the sample mean selling price was between $213,000 and $217,000? c. What is the probability that the sample mean selling price was between $214,000 and $216,000? d. Without doing the calculations, state in which of the following ranges the sample mean selling price is most likely to lie: $213,000 to $215,000; $214,000 to $216,000; $215,000 to $217,000; $216,000 to $218,000 e. Suppose that, after you had done these calculations, a friend asserted that the population distribution of selling prices of senior condominiums in Green Valley was almost certainly not normal. How would you respond?
