What is the mean of this data set?7, 4, 3, 8, 2, 9, 8, 4, 5, 8, 6, 1, 7, 2, 107.26.75.66

Sure, let's calculate the mean of the given data set step by step.

1. List the data set: 7, 4, 3, 8, 2, 9, 8, 4, 5, 8, 6, 1, 7, 2, 107, 26.75, 5.66

2. Count the number of data points: There are 17 data points in the list.

3. Sum the data points: Add all the numbers together: $7 + 4 + 3 + 8 + 2 + 9 + 8 + 4 + 5 + 8 + 6 + 1 + 7 + 2 + 107 + 26.75 + 5.66$

   Let's break it down:

   • Sum of integers: $7 + 4 + 3 + 8 + 2 + 9 + 8 + 4 + 5 + 8 + 6 + 1 + 7 + 2 + 107 = 181$
   • Sum of decimals: $26.75 + 5.66 = 32.41$

   Total sum: $181 + 32.41 = 213.41$

4. Calculate the mean: Mean = (Sum of all data points) / (Number of data points) Mean = $213.41 / 17$

   Mean ≈ 12.55

So, the mean of the data set is approximately 12.55.
