25
Right.
200 / 8 = 25
To find the mean of a data set, you need to add up all the values in the data set and then divide the sum by the total number of values. Let's go through the steps to find the mean of the given data set:
1. Add up all the values: 25 + 30 + 20 + 20 + 25 + 35 + 35 + 10 + 15 + 20 + 25 + 30 = 290.
2. Count the total number of values in the data set: There are 12 values in the set.
3. Divide the sum of all the values by the total number of values to find the mean: 290 รท 12 = 24.17.
Therefore, the mean of the given data set is approximately 24.17.
