To find the mean you add all the numbers and divide by how many numbers there are so in this case 2+3+4+4+6= 19, there are 5 numbers so divide 19/5
Consider that 100%-72%=28% represents the percentage of wrong answers. I would think as fractions as:
if 100% is the total number of answers and 28% are the wrong ones
as
if x is the total you have 14 wrong you can write:
x=(100/28)*14=50 questions
Range of the data = 13
Solution:
To find the range of the given data:
Let us first define what is range.
Range:
The range of the data set is the difference between the highest value and lowest value of the data set.
i. e. Range = Highest value – Lowest value
In the given number line,
Highest value indicated = 115
Lowest value indicated = 102
Range of the data = 115 – 102
= 13
Range of the data = 13
Hence the range of the given data is 13.
