If you have the data set {2, 4, 6, 9, 3}, what is the mean?

The correct answer is: 4.8

To find the mean of a data set, you add all the numbers together and then divide by the total number of data points. In this case, the data set is {2, 4, 6, 9, 3}. First, you calculate the sum of the numbers: 2 + 4 + 6 + 9 + 3 = 24. Next, count the number of items in the set, which is 5. Now, divide the total sum by the number of data points: 24 ÷ 5 = 4.8. Thus, the mean of the data set is 4.8. This is why B is the correct answer. The calculation shows that the average value of the numbers in the set is 4.8, representing the central tendency of the data.
