The Frequency × midpoint column is completed by multiplying the values in the Frequency (f) column with the corresponding values in the Midpoint (x) column. Here's how it's done:

1. For the first row, the frequency is 8 and the midpoint is 5. Multiply these together to get 40. So, the value for the first row in the Frequency × midpoint column is 40.

2. For the second row, the frequency is 10 and the midpoint is 15. Multiply these together to get 150. So, the value for the second row in the Frequency × midpoint column is 150.

3. For the third row, the frequency is 12 and the midpoint is 25. Multiply these together to get 300. So, the value for the third row in the Frequency × midpoint column is 300.

4. For the fourth row, the frequency is 14 and the midpoint is 35. Multiply these together to get 490. So, the value for the fourth row in the Frequency × midpoint column is 490.

5. For the fifth row, the frequency is 6 and the midpoint is 45. Multiply these together to get 270. So, the value for the fifth row in the Frequency × midpoint column is 270.

So, the completed Frequency × midpoint column is: 40, 150, 300, 490, 270.
