Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.

Annual incomes are known to have a distribution that is skewed to the rnight instead of being normally dis sample of annual incomes. Can the distribution of incomes in that sample be approximated by a normal distibution because the sample is large? right instead of being normally distributed Assume that we cllect a large (n> 30) random Why or why not?
