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?
The National Institute of Diabetes and Digestive and Kidney Diseases reports that the average cost of bariatric (weight loss) surgery is about $22,500. You think this information is incorrect. You randomly select 30 bariatric surgery patients and find that the average cost for their surgeries is $21,545 with a standard deviation of $3015. Is there enough evidence to support your claim at Use a P-value. area of the result of z = 0.0418 1. determine the value of z 2. determine the value of P 3. decision
According to a construction company plan, a project must be implemented in three consecutive stages during six months. The chance that the first stage is completed on time is (0.5). The chance that the second stage is completed on time is (0.3) given that the first stage is completed on time. The chance that the third stage is completed on time is (0.2) given that both the first and the second stages are completed on time. Accordingly, the probability will be equal to (1) when all three stages .are completed on time True O False O

A contractor is planning the acquisition of construction equipment, including bulldozers, needed for a new project in a remote area. Suppose that from his prior experience with similar bulldozers, he estimated that there is a 65% chance that each bulldozer can remain operational for at least 6 months. 1.) If he purchased four bulldozers for the new project, what is the probability that there will be at least two bulldozers left operational after six months into the project? .
