To find the mean of a data set, you need to sum up all the values and divide by the number of values.
Sum = 20 + 24 + 29 + 30 + 38 + 49 = 190
Number of values = 6
Mean = Sum / Number of values = 190 / 6 = 31.67
So, the mean of the given data set is 31.67.
What is the mean of the following data set?
{20, 24, 29, 30, 38, 49}
