A bar graph entitled Lifetime Pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20.

Answer 2

The true statement about the number of pets owned by the thirty adults is (b) The mean and median are both in the interval 6-10

What is an histogram?

Histograms are graphs that are used to represent data, where the length of the bars represent the frequency

The data on the histogram are:

14 adults = 1-5 pets;

9 adults = 6 to 10 pets;

5 adults = 11 to 15 pets

2 adults = 16 to 20 pets

The mean is calculated as:

$\bar x = \frac{\sum fx}{\sum f}$

So, we have:

$\bar x = \frac{14 * 3 + 9 * 8 + 5 * 13 + 2 * 18}{30}$

This gives

$\bar x = 7.2$

7.2 is in interval 6 to 10

The median is:

$Median = \frac n2$

$Median = \frac {30}2$

$Median = 15th$

The 15th element is also interval 6 to 10

Hence, the true statement is (b) The mean and median are both in the interval 6-10
