Complete the table to find the deviation of each data point. The mean is 9.25. The data points are 7, 9, 9.5 and, 12. What are the deviations?

Answer 1

To find the deviations of each data point from the mean, you'll subtract the mean from each data point. The mean is 9.25.

Here are the calculations:

1. For the data point 7: \[ \text{Deviation} = 7 - 9.25 = -2.25 \]

2. For the data point 9: \[ \text{Deviation} = 9 - 9.25 = -0.25 \]

3. For the data point 9.5: \[ \text{Deviation} = 9.5 - 9.25 = 0.25 \]

4. For the data point 12: \[ \text{Deviation} = 12 - 9.25 = 2.75 \]

Now, let's summarize the deviations in a table:

| Data Point | Deviation | |------------|-----------| | 7 | -2.25 | | 9 | -0.25 | | 9.5 | 0.25 | | 12 | 2.75 |

These are the deviations of each data point from the mean.

Answer 2

The deviations for points 7 and 9 are wrong
