PROBLEM 3: The square footage of several thousand apartments in a new development is advertised to be 1250 square feet, on average. A tenant group thinks that the apartments are smaller than advertised. They hire an engineer to measure a sample of apartments to test their suspicions. Let u represent the "true" mean area (in square feet) of these apartments. What are the appropriate null and alternative hypotheses? PROBLEM 4: Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet? Let u denote the population mean height of all adult American males between the ages of 18 and 21. What are the appropriate null and alternative hypotheses?

The next time you make a trip to a supermarket, ask the manager if you can measure the mass of at least 10 cereal boxes of your choice. Choose the same brand and the same size boxes. Tell the manager this is an assignment for a class. Report the average mass, variance, and standard deviation for the cereal boxes. Does the manufacturer’s information noted on the box fall within your measurement?

2. If an activity whose normal duration is 15 days can be shortened to 10 days for an added cost of $2,000, what is the crash time and crash cost per day? Select one: a. 10 days; $400 b. 10 days; $2,000 c. 5 days; $10,000 d. 10 days; $20,000 e. 5 days; $400
The duration of a construction project lasts between 121 and 160 days. There is an equal chance for the duration to be equal for any number of days between 121 and 160 days. Currently the project is scheduled to be finished in 130 days or fewer. compute the probability that the project will be finished on time.

Storm doors have been installed on 50% of all homes in Anytown, USA. The remaining 50% of homeowners without storm doors think they may have a problem that a storm door could solve, but they’re not sure. Use Activities 1, 2, and 3 in the engineering design process to help these home owners systematically think through the definition of their need (Activity 1), a formal statement of their problem (Activity 2), and the generation of alternatives (Activity 3). The design process begins in the shown Figure with a statement of need and terminates with the specifications for a means of fulfilling that need.
