Christina is conducting a study regarding children and exercise. She surveyed a sample of children regarding their daily exercise times, rounded to the nearest minute, and she recorded her findings in the histogram below. According to the histogram above, what is the range of the median daily exercise time?

The median daily exercise class range is 30 minutes

Reason for the above range:

The median of the histogram is given as follows;

The width of each bar = 30

The total area of the histogram = 30×50 + 30×60 + 30×10 + 30×5 = 3,750

The median = 3,750/2 = 1,875

The area of the first class = 30×50 = 1,500

The area of the second class = 30×60 = 1,800

The difference between the median and the area of the first class = 1,875 - 1,500 = 375

The median is therefore larger than the first class but within the second class

The depth within the second class the median is located = 375/60 = 6.25

The median best estimate = (30 + 6.25) minutes = 36.25 minutes

Range =

The range of the median class interval = between 31 and 60 minutes = 30 minutes

30

Step-by-step explanation:

median from the given data; 50, 60, 10, 5

arrange in order: 5, 10, 50, 60

The median is a measure of central tendency. It represents the value for which 50% of observations a lower and 50% are higher. Put simply, it is the value at the center of the sorted observations.

therefore,

the median = (10 + 50) / 2

                  = 30

the y will be in still but your answer will be y x 3
