10. A random sample of n = 25 is selected from a normally distributed population with u = 600 and O = 100. What is the probability that the sample mean will be less than 590? • What is the z-score for this sample mean? Please show your work, draw your distribution, and place the z-score for this mean on the distribution. What proportion of sample means would be expected to be less than this sample mean? Indicate where this area is on your distribution. You can shade it in or draw an arrow. What proportion of sample means would be expected to be greater than this sample mean? Indicate where this area is on your distribution. You can shade it in using a different color or draw an arrow.
