Question

the histogram below displays the distribution of 57 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 40? (round your percentage to 1 decimal place) enter an integer or decimal number more.. question help: written example message instructor

Explanation:

Step1: Count frequencies for ages < 40

From the histogram, frequencies for ages 10 - 20, 20 - 30, 30 - 40 are 6, 20, 10 respectively. Sum them: $6 + 20+10=36$.

Step2: Calculate the percentage

Use the formula $\text{Percentage}=\frac{\text{Number of individuals younger than 40}}{\text{Total number of individuals}}\times100\%$. Total number of individuals is 57. So, $\text{Percentage}=\frac{36}{57}\times 100\%\approx 63.2\%$.

Answer:

$63.2$
