The average cost of a condominium study in the Cedar Lakes development is
$ 62,000 with a standard deviation of $ 4,200 (for a n = 25).
a) What is the probability that a condominium in this development will cost at least
 $ 65,000?
b) The probability that the average cost of a sample is between $ 65,000 and
62,000?
c) With the above information, what would be the intervals for the following levels of
trust:
(1) 67%:
(2) 95%:
(3) 99%:

In a group of 66 Mummers, the average income was $62,000 with a standard deviation of $22,000. We are interested to determine if the average income of a Mummer is significantly different than $50,000. Write the appropriate null and alternative hypotheses for the hypothesis test that is relevant to this problem. Find the test statistic. Find the critical value for α=0.05. What is the result of the hypothesis test? Why?

Rosenberg Land Development (RLD) is a developer of condominium properties in the Southwest United States. RLD has recently acquired a 40.625 acre site outside Phoenix, Arizona. Zoning restrictions allow at most 8 units per acre. Three types of condominiums are planned: one-, two-, and three-bedroom units. The average construction costs for each type of unit are $450,000, $600,000 and $750,000, respectively. These units will generate a net profit of 10%. The company has equity and loans totaling $180 million dollars...
