Question:
Halifax: 186,600 Quebec City: 356,800 Oshawa: 148,100 Winnipeg: 381,300 Saskatoon: 121,600 Victoria: 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 standard deviation of the log x values is equal to log s.
e. The following exercise summarizes parts (b) and (c): For the body temperature data listed in Data Set 18 of Appendix B (first 10 scores), x = 36.36°C and s = 0.35°C. Find the values of x and s for the data after each temperature has been converted to the Fahrenheit scale.
