Question

Find the mean of the data set shown in the table below.
Data Set EData Set E
1, point, 6, 91.69
0, point, 8, 50.85
0, point, 2, 30.23
1, point, 61.6
0, point, 0, 80.08

Answer 1

To find the mean of Data Set E, we first need to summarize the numbers correctly and then perform the following steps:

1. **List the Data**: The data points are:
- 1.691
- 0.850
- 0.230
- 1.616
- 0.080

2. **Sum the Data Points**: Add all of these values together.
\[
1.691 + 0.850 + 0.230 + 1.616 + 0.080 = 4.467
\]

3. **Count the Number of Data Points**: There are 5 data points.

4. **Calculate the Mean**: Divide the sum by the number of data points.
\[
\text{Mean} = \frac{4.467}{5} = 0.8934
\]

Thus, the mean of Data Set E is **0.8934**.
