Question

Here is a stemplot of the percents of residents aged 65 and older in the 50 states: Find and interpret the percentile for Colorado, which has 10.1 of its residents aged 65 or older.

Answer 1

To find the percentile for Colorado in the stemplot, divide the number of states below Colorado by the total number of states and multiply by 100%.

Step-by-step explanation:

The stemplot represents the percents of residents aged 65 and older in the 50 states. To find and interpret the percentile for Colorado, which has 10.1% of its residents aged 65 or older, we need to count the number of states with a lower percentage than Colorado. From the stemplot, we can see that there are 21 states with a lower percentage than Colorado. Since there are 50 states in total, we can calculate the percentile as:

Percentile = (Number of states below Colorado / Total number of states) × 100%
= (21 / 50) × 100%
= 42%

This means that Colorado is at the 42nd percentile, indicating that it has a relatively low percentage of residents aged 65 or older compared to other states.
