Answer:
[tex]Median = 75[/tex]
Explanation:
Given
[tex]n = 33[/tex]
See attachment for histogram
Required
Determine the median
Median is calculated as:
[tex]Median = \frac{n+1}{2}th[/tex]
[tex]Median = \frac{33+1}{2}th[/tex]
[tex]Median = \frac{34}{2}th[/tex]
[tex]Median = 17th[/tex]
From the histogram, the 17th entry fall in the class: 70 - 80
In this case: the median is the average of 70 and 80
So:
[tex]Median = \frac{1}{2}(70 + 80)[/tex]
[tex]Median = \frac{1}{2}(150)[/tex]
[tex]Median = 75[/tex]
