Computer Lab 12a A random sample of size 36 is drawn from a population that is slightly skewed left with a mean of 100 and a standard deviation of 12. 1. What is the shape of the sampling distribution of the sample mean X? Explain why? 2. What is the mean of the sampling distribution of the sample mean X? 3. What is the standard deviation of the sample mean X? 4. What is the probability of obtaining a sample mean less than 102
