A study was conducted to investigate the ages of college students. Let X = the age of a college student 1. Suppose X follows a distribution skewed to the right. What is true about the shape of the distribution of , the mean age X-bar , for a sample of 100 college students? 2. As the sample size increases, how does that affect the mean for the distribution of X-bar? Group of answer choices   3.  Which of the following has the smallest standard deviation? I.  The distribution for X = the age of a college student II.  The distribution for  X-Bar = the average age for a sample of 100 college students III.   The distribution for  X-Bar = the average age for a sample of 400 college students
