Chapter 18 (Page 483): #34: Assessment records indicate that the values of homes is skewed right, with mean $140,000 and standard deviation $60,000. We sample 100 homes at random. Use rule, draw and label and appropriate sampling model for the mean value of the homes selected. Mean = 140,000 SD = 6,000

Use Normal tables or technology for the following.
