2.) A real estate agent has 10 properties that she shows. She
feels that there is a 50% chance of selling anyone property during
a week. The chance of selling any one property is independent of
selling another property. Compute the probability of selling more
than 2 properties in one week.
3.) A manager records the repair cost for 31 randomly selected
washers. A sample mean of 84.87 dollar and standard deviation of
12.34 dollar are subsequently computed. Determine a 90% confidence
interval for the mean repair cost for the washers. Assume the
population is normally distributed.
