QUESTION 1 The sale prices of houses in a local community have an average of $210,000 and a median of $135,000. This means half of the houses are priced under $135,000. This means that there are a few really low-priced houses because the mean is so low. This means half of the houses are priced over $210,000. If you are buying a house in this community, you will pay $210,000 for the house. QUESTION 2 A production line is manufacturing ball bearings for engines. A particular run of bearings is supposed to have a diameter of 2". The average of the run is 2". Which one of the following standard deviations would indicate the best production? 0001" .001" 01" 0.1" QUESTION 3 When comparing regression models, the R2 with the value closest to 1 is usually best. True: False
