Suppose the change in price from 2012 to 2013 for 10 houses in Toronto is measured (in percent) for a study to determine the possibility of a financial bubble in the real estate market. The change, in percent, for a sample of 10 houses was recorded as: 0, 5, -10, -15, 10, 20, 15, -10, -5, and -10. a) For this experiment, what is the variable of interest and the statistical population? b) What is the median change in price for the sample. c) Find the sample mean and the sample standard deviation. d) Find the quartiles of the sample and the z-score of the percentage price change equal to 12 (for standard deviation use 12). e) Draw a boxplot and determine if there is any outlier.
