Calculate the mean of the data set 3, 5, 7, 9.

Explanation:
Mean is found by adding all the numbers and dividing by how many numbers there are. For 3, 5, 7, 9, the sum is 3 + 5 + 7 + 9 = 24. There are four data points, so 24 divided by 4 gives 6. So the mean is 6. The other options would require a different total or a different count (for example, 4 would imply a total of 16 across four numbers, 5 would imply 20, and 9 would be the largest value rather than the average).
