a. Find the mean, median, mode, and midrange for the following labour force populations (based on data from Statistics Canada):
Halifax: 186,600 Quebec City: 356,800 Oshawa: 148,100
Winnipeg: 381,300 Saskatoon: 121,600Victoria: 164,600
b. If a constant value k is added to each population, how are the results from part (a) affected?
c. If each population given in part (a) is multiplied by a constant k, how are the results from part (a) affected?
d. Data are sometimes transformed by replacing each score x with log x. For the given x values, determine whether the mean of the log x values is equal to log x.
