Chapter 2 Notes

The histogram below displays the distribution of 50 ages at death due to trauma (accidents and homicides) that were observed in a certain hospital during a week. What percentage of deaths were individuals younger than 35? (a) 34% (b) 60% (c) 68% (d) 70% (e) 80% Solution From the histogram we can find that 3 + 18 + 13 = 34 out of the 50 observations fall below age 35 (those within the first three bars), and since the question asks about the percentage of observations, the answer is (34/50) * 100 = 68%.
