11. The effect of transformations of scale on the mean and standard deviation You just completed a small research project for your psychology class concerning'the effects of an event that happened two years ago on women's opinions and actions today. The mean age of participants in your study is 25.4 years with a standard deviation of 3.6 years. As you write up your results, you realize that what matters is the ages of the participants two years ago when the event happened, not their ages now. You decide to subtract 2 from each of your participants' ages. After you subtract 2 years, the mean age in your sample is ___V_ years. The new standard deviation of the ages in your sample is L years. One of the variables you collected was the study participants' heights in centimeters. The mean height of participants in your study is 168.1 centimeters with a standard deviation of 8.405 centimeters. Your professor, however, requested that you report this value in inches. To convert from centimeters to inches, you multiply by 0.394. After you multiply the heights of your participants by 0.394, the mean height in your sample is v inches. The new standard deviation of the heights in your sample is v inches
