According to insurance company tables, U.S. men who are currently 50 years of age have an average life expectancy of 80 years with a standard deviation of 8 years. Assume life expectancy is normally distributed in this population. Hint: in order to answer the next few questions it may be helpful to draw a normal distribution with mean = 80 and standard deviation = 8. Use Table E.10 in the appendix of your textbook (or other resources) to determine probabilities or percentiles associated with z-values What percent of these men would be expected to die between 76 and 84 years of age? 1. Approximately 38% 2. Approximately 20% 3. Approximately 68% 4. Approximately 19%
