For instance, to project home run totals during the "dead ball era" (the era from about 1900 to 1919) to those of today, statisticians might use the transformation y = 2x+15.5, where y is a modern home run total and x is a home run total from the dead ball era. Suppose that the mean home run total among top players during one season in the dead ball era was 3.5, with a standard deviation of 1.7. 1. If these dead ball era home run totals were projected to modern home run totals, what would their || mean be? Do not round your response. 2.
