s there a risk to being too focused on the financial aspects of the property? What type of strategy would you develop to maximize the value of your property?
1. Would you charge the highest possible rents? Why or why not?
2. Would you maintain the property to the highest possible levels of quality and cleanliness at all times? Why or why not?
3. Would you take any tenant so long as they paid the rent? Why or why not?
Explain and discuss.

The average number of pages for a simple random sample of 40 physics textbooks is 435. The average number of pages for a simple random sample of 30 mathematics textbooks is 410. Assume that all page length for each types of textbooks is normally distributed. The standard deviation of page length for all physics textbooks is known to be 55, and the standard deviation of page length for all mathematics textbooks is known to be 55. Part One: Assuming that on average, mathematics textbooks and physics textbooks have the same number of pages, what is the probability of picking samples of these sizes and getting a sample mean so much higher for the physics textbooks (one-sided p-value, to four places)?WebAssign will check your answer for the correct number of significant figures. The above p-value comes from a test-statistic of z=WebAssign will check your answer for the correct number of significant figures. (enter number without sign).

4. The number of students arriving at a university’s health
center is Poisson distributed with a mean of 4.5 students
per hour. Use the appropriate formulas provided in class to
determine the probability that:
a. four students will arrive at the health center in the next
hour.
b. more than 10 minutes will elapse between student arrivals at the
health center.

The Mean number of words per minute (WPM) read by sixth graders is 98 with a standard deviation of 20. If 57 sixth graders are randomly selected, what is the probability that the sample mean would differ from the population mean by greater than 4.41 WPM?

Seventy percent of households say they would feel secure if they had $50,000 in savings. You randomly select 8 households and ask them if they would feel secure if they had $50,000 in savings. Find the probability that the number that say they would feel secure is:
(a) exactly five,
(b) more than five,
(c) at most five.

Based on historical data, your manager believes that 44% of the
company's orders come from first-time customers. A random sample of
59 orders will be used to estimate the proportion of
first-time-customers. What is the probability that the sample
proportion is between 0.33 and 0.49?
