Suppose a subdivision on the southwest side of Denver, Colorado, contains 1,800 houses. The subdivision was built in 1983. A sample of 110 houses is selected randomly and evaluated by an appraiser. If the mean appraised value of a house in this subdivision for all houses is $229,000, with a standard deviation of $8,500, what is the probability that the sample average is greater than $231,000?

This problem will take you through calculating the mean for grouped data by hand.The reason that the class midpoint is used in the table below is because it is the expected value for the average score in each class. Part A: Lower Class Limit Upper Class Limit Frequency Class midpoint Frequency times midpoint 40 44 1 45 49 3 50 54 4 55 59 11 57 627 60 64 20 62 1240 65 69 13 67 871 70 74 7 72 504 75 79 7 77 539 80 84 1 82 82 Part B: Now add up the last column of the table above. Part C: Now add up the third column of your table. Part D: Now divide your answer to Part B by your answer to Part C. This is the mean for the Grouped Frequency Data Table (GFDT).
