You're setting sales goals for next month. you base your goals on previous average sales. the actual sales for the same month for the last 4 years have been 24 units, 30 units, 23 units, and 27 units. what is the average number of units you can expect to sell next month?

To find the previous average sales, add the units sold in the same month in each of the last 4 years: 24 + 30 + 23 + 27 = 104. Then divide the sum by the number of different values, which in this case is 4. 104/4 = 26. Since sales goals are based on the previous average sales, you should expect to sell 26 units next month.
