Consider two populations of coins, one of pennies and one of quarters. A random sample of 25 pennies was selected, and the mean age of the sample was 32 years. A random sample of 35 quarters was taken, and the mean age of the sample was 19 years. For the sampling distribution of the sample means, have the conditions for normality been met? A. No, the conditions for normality have not been met for the quarters or the pennies. B. No, the conditions for normality have not been met for the quarters. C. No, the conditions for normality have not been met for the pennies.
