Whoever answers this will get 75 point! how do i find the mean, give the process, of the data set? city a: {3, 4, 6, 4, 3, 1, 4} city b: {6, 7, 2, 4, 5, 5, 3}

Step-by-step explanation:

Mean is just another word for average.  To find the average, add up all the values then divide by the number of values.

There are 7 values in the first data set.  The average is:

(3 + 4 + 6 + 4 + 3 + 1 + 4) / 7 = 25/7 ≈ 3.57

There are 7 values in the second data set.  The average is:

(6 + 7 + 2 + 4 + 5 + 5 + 3) / 7 = 32/7 ≈ 4.57

16.80 times .20= 3.36
