Final answer:
The mean of the given series of numbers is 4.3.
Step-by-step explanation:
The mean is the average of a set of numbers. To find the mean, add up all the numbers in the set and divide the sum by the total number of numbers. In this case, the set of numbers is 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 7. Adding up all the numbers gives us a sum of 60. Since there are 14 numbers in the set, the mean is 60 divided by 14, which equals 4.2857. Rounded to one decimal place, the mean is 4.3.
