Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 9 milliondollars and a standard deviation of 1.4 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarteris in the bottom 10% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered"failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimalplace.

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 9 million dollars and a standard deviation of 1.2 million dollars. One health care information systems company considers a quarter a “failure” if it’s sales level that quarter is in the bottom 15% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered “failure” by that company and quarters that are not. Carry your intermediate computations to atleast four decimal places and round your answer to one decimal place.
13. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. Find the range in which at least 68% of the data will lie. Use the Empirical Rule.
An estimated 1.6 million students take on student loans to pay ever-rising tuition and room and board (The New York Times, April 17, 2009). It is also known that the average cumulative debt of recent college graduates is about $21,700. Let the cumulative debt among recent college graduates be normally distributed with a standard deviation of $9,000. Approximately how many recent college graduates have accumulated a student loan of more than $30,000? (You may find it useful to reference the z table. Round "z-value" to 2 decimal places.)
Suppose that the life-span of goldfish can be modeled by the Normal Distribution with a mean of 5 years and a standard deviation of 2.3 years. What is the life span of the 90th percentile of goldfish? Interpret this value. The 90th percentile is 7.95 years. This means that 90% of goldfish will have lifespans less than or equal to 7.95 years. The 90th percentile is 2.05 years. This means that 90% of goldfish will have lifespans greater than or equal to 2.05 years. The 90th percentile is 2.05 years. This means that 90% of goldfish will have lifespans less than or equal to 2.05 years. O The 90th percentile is 7.95 years. This means that 90% of goldfish will have lifespans greater than or equal to 7.95 years.
Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 11 million dollars and a standard deviation of 1.4 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 10% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
