Question

On the most recent district-wide math exam, a random sample of students earned the following scores:

Answer 1

Answer:

mean=80.833

median=84.5

Step-by-step explanation:

scores:

95,45,37,82,90,100,91,78,67,84,85,85,82,91,93,92,75,84,100,59,92,77,68,88

we arrange the scores in ascending order

37,45,59,67,68,75,77,78,82,82,84,84,85,85,88,90,91,91,92,92,93,95,100,100

mean=sum of all observations/total number of observations

        = 1940/24

        =80.833

median is the central tendency of all observations

median lies between 84 and 85

median=(84+85)/2

           = 84.5
