Question

percentage of population supplied by water supply industry
a census was taken in 11 african countries. for each country, the amount of the population that had access to water from the water supply industry was computed and recorded to the nearest 5 percent. this amount was expressed as a percentage of the total population and plotted. according to the dot plot, what is the range of these percentages?
(ignore the % when entering your answer. for example, if the answer is 11%, enter 11)

Explanation:

Step1: Identify max and min values

From the dot plot, the minimum percentage is 30 (the leftmost dot) and the maximum percentage is 100 (the rightmost dot).

Step2: Calculate the range

Range is calculated as maximum value minus minimum value. So, \( 100 - 30 = 70 \).

Answer:

70
