To evaluate the statistics for the given situation
Answer to Problem 6CR
Mean of the new data set can be found by adding 4 to the mean’s original data set value.
Explanation of Solution
Given information:
Data set vales are increased by 4.
Statistic will be increased by +4
The formula for mean is,
Let the data set consists of x1 , x2andx3
Therefore, substituting in the formula.
The new data is,
( x1 +4),( x2 +4),( x3 +4)
Hence, for mean,
Opening the brackets,
On solving,
So,
So,
Substituting (1),
Hence, Mean of the new data set can be found by adding 4 to the mean’s original data set value.
