To estimate a population mean u, the sample mean ī is often used as an estimator. However, a different estimator is called the sample midrange, given by the formula sample minimum + sample maximum (c) The following table shows the values, in thousands of dollars, of 40 randomly selected houses in the city. 34 95 155 155 38 110 137 140 169 207 217 314 314 343 347 209 274 323 349 363 397 416 487 369 373 388 389 448 450 483 516 571 595 762 488 600 738 769 863 1,084 (1) Calculate the sample midrange for the data. (ii) Explain why the sample midrange might be preferred to the sample mean as an estimator of the population mean.
