study of the life expectancy

For Exercises 26 and 27, check to see whether the correction factor should be used. If so, be sure to include it in the calculations.

25.   Life Expectancies In a study of the life expectancy of 500 people in a certain geographic region, the mean age at death was 72.0 years, and the standard deviation was

5.3 years. If a sample of 50 people from this region is selected, find the probability that the mean life expectancy will be less than 70 years.

26.   Home Values A study of 800 homeowners in a certain area showed that the average value of the homes was

$82,000, and the standard deviation was $5000. If 50 homes are for sale, find the probability that the mean of the values of these homes is greater than $83,500.
