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

You have data for only three months. What is the data for the fourth year?

To find the average number of units you can expect to sell next month based on the previous average sales, you need to add up the sales from the last four years, then divide the sum by the number of years.

Here's how you can calculate it:

1. Add up the sales for the last four years: 24 + 30 + 27 = 81.

2. Divide the sum by the number of years (which is 3 in this case, as we're considering the average only for the last three years): 81 / 3 = 27.

So, the average number of units you can expect to sell next month is 27 units based on the previous average sales.
