Question 1

The board of examiners that administers the real estate broker's examination in a certain state found that the mean score on the test was 419 and the standard deviation was 72. If the board wants to set the passing score so that only the best 80% of all applicants pass, what is the passing score? Assume that the scores are normally distributed.

Question 2

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 2600 miles. If the manufacturer guarantees the tread life of the tires for the first 56,880 miles, what proportion of the tires will need to be replaced under warranty?
