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 population of incomes is not normally distributed, so the sample means will not be normally distributed for any sample size.
d. no, the sample means will be normally distributed, but the sample of incomes will be skewed to the right.
