A variable of a population has a mean of 100 and a standard deviation of 28. Consider the sample distribution of samples means of sample size 49. a. What is the mean of sample means? b. What is the standard deviation of the sample means? c. Is the distribution of sample means normal? Why or why not? Do we need to know if the variable in question is normally distributed in the population? Why or why not?
