A used concrete pumping truck can be purchased for $125,000. The operation costs are expected to be $65,000 the first year and increase 5% each year thereafter. As a result of the purchase, the company will see an increase in income of $100,000 the first year and 5% more each subsequent year. The company uses straight-line depreciation. The truck will have a useful life of five (5) years and no salvage value. Management would like to see a 10% return on any investment. The company's tax rate is 28%.
All of the following are characteristics of standard normal distribution, except:
The statement that the 'means and median are not equal' is incorrect for a standard normal distribution. In a standard normal distribution, the mean, median, and mode are all equal, as the distribution is perfectly symmetrical. The correct characteristics of a standard normal distribution are that approximately 68% of the values fall within one standard deviation of the mean, the total area under the curve is 1, and the curve shape is symmetrical.
