Answer 1

-6.86 %

Step-by-step explanation:

The percent of chance can be calculated as:

`\frac{_{}\text{ final - initial}}{\text{ initial}}*100`

So, replacing the final value by 52.5 years and the initial value by 56.1 years, we get:

`(52.5-56.1)/(52.5)*100=-6.86\text{ \%}`

Therefore, the percent change of life expectancy was -6.86 %. Where the negative sign means that there was a decrease in the average life expectancy.
