Information about ocean weather can be extracted from radar returns with the aid of a special algorithm. A
study is conducted to estimate the difference in wind speed as measured on the ground and via the Seasat
satellite. To do so, wind speeds (miles per hour) are measured on the ground and via the Seasat satellite
simultaneously at 12 special times. The data is shown in the following table. The table also shows the difference
between the wind speed on the ground and that via the Seasat satellite at each time, as well as some summary
statistics.

The value of the number will be the weighted sum of each of the digits. The leftmost digit has the greatest positional weight, while the rightmost has the least. The digits of our number system have weights that are powers of k, where k is the number of symbols we are using. The right most digit has weight kº. The digit to its left will have weight k¹, then k², and so on.
