2 If n-40, describe the sampling distribution of. a) Center: = ??? b) Spread: SE - ??? Round to 1 decimal place. c) From the given information what can we say about the shape of the sampling distribution of x bar? 1. It is impossible to know the distribution of x bar given the information. 2. The distribution of x bar is not approximately normal the population is not normal. 3. The distribution of x bar is approximately normal because the sample size is large, in other words, n30. 4. The distribution of is not approximately normal because the sample size is small, in other words, n
