Question:
The distribution of IQs is said to have a mean of 100 and a standard deviation of 15. Suppose a company was selling IQ+ pills so that those that took it would magically have their IQs transformed by the equation: New IQ = 1.05(Old IQ) + 10. If everyone took this pill (and it worked as advertised), what would be the mean and standard deviation of the distribution of new IQs?
A. Mean = 115, SD = 25.75
B. Mean = 105, SD = 25.75
C. Mean = 115, SD = 15.75
D. Mean = 105, SD = 15.75
E. Mean = 110, SD = 25
