Annual incomes are known to have a distribution that is skewed to the right instead of being normally distributed. assume that we collect a large (ngreater than30) random sample of annual incomes. can the distribution of incomes in that sample be approximated by a normal distribution because the sample is large? why or why not? choose the correct answer below. a. yes; the sample size is over 30, so the sample of incomes will be normally distributed. b. no; unless more than 30 samples are collected, the sample of incomes will not be normally distributed. c. no; the sample means will be normally distributed, but the sample of incomes will be skewed to the right. d. no; the population of incomes is not normally distributed, so the sample means will not be normally distributed for any sample size.
