question 68

Multiple Choice

The preventable monthly loss at a company has a normal distribution with a mean of $7800 standard deviation of $30. A new policy was put into place, and the preventable loss the next month was $7620. What inference can you make about the new policy?

• A) The new policy is probably less effective than the one it replaced.
• B) Because the probability that the monthly loss would be as low as $7620 is small, the new policy is working.
• C) Because the probability that the monthly loss would be as low as $7620 is not very small, the new policy is not working.
• D) While the probability that the monthly loss would be as low as $7620 is small, it is not unexpected.
