The average cost of a one-bedroom apartment in a town is $650 per month. What is the probability of randomly selecting a sample of 50 one-bedroom apartments in this town and getting a sample mean of less than $630 if the population standard deviation is $100? (Round the values of z to 2 decimal places. Round your answer to 4 decimal places.)

At a cost of $10,000, Sleepy purchased a car three years ago for personal use. In the current year, she dozed off one night while driving and the car attached itself to a tree. Before the accident, the car was worth $8,000 but, after the accident, only $1,000. At the time of the accident Sleepy was taking a vase, a decorative ornament in her home, to a dealer to have it appraised. It had been purchased two years earlier for $10,000, and it was totally destroyed in the accident. Sleep recovered $1,000 in insurance for the car and $20,000 for the vase. Disregarding the above transactions Sleepy has an adjusted gross income of $30,000.
What is the amount of Sleepy’s personal casualty loss on the car for the year?
What is the amount of Sleepy’s personal casualty gain on the vase for the year?
What is the character of those gains and losses?

.A machine cost $200,000 and has a salvage value of $100,000 if kept for one year. The salvage value will decrease by $50,000 in years 2 and 3 and remain zero after year 3. The operating costs are $50,000 the first year and increase by $50,000 per year. So operating costs in year two will be $100,000, and in year three $150,000 and so on. How long should the equipment be kept so that annual cost is minimized if the MARR is 10%/year compounded annually or stated another way what is the economic service life (ESL) and what is the associated annual cost for this service life?

For each of 12 organizations, the cost of operation per client was found. The 12 scores have a mean of $2133 and a standard deviation of $345. Assume the population of cost of operation per client follows a normal model. Compute and interpret a 90% CI for the mean cost of operation for all such organizations
