A sample of 81 condominiums has an average selling price of $51500 with a standard deviation of $8500. I 8 . The standardized test statistic calculated for a hypothesis test of whether the sample mean is equal to the hypothesized population mean is equal to: a, 1.56 b. 1.57 c. 1.59 9. The probability value of the event that the standardized test statistic would assume a value as extreme or more extreme as that calculated in part 12 is: a, 0.01 b 0.112 c. 0.116 10. By comparing the probability value calculated in question 13 with a level of significance of 0.01 in a hypothesis test, we cannot reject the statement that: a. the mean price of a condominium in Naples, Florida is not equal to $50000. b. the mean price of a condominium in Naples, Florida is greater than $50000 c, the mean price of a condominium in Naples, Florida is equal to $50000. 11. The 99% confidence interval for the population mean price of condominiums in Naples, Florida will fall between a. (49000, 54000) b. (49008, 53992) C. (49067, 53933) United States) [ Focus
