To Make:Prediction of a student with 12 weeks’ experience with the data given below:
Experience(Weeks) | 4 | 7 | 8 | 1 | 6 | 3 | 5 | 2 | 9 | 6 | 7 | 10 |
Speed(WPM) | 38 | 46 | 48 | 20 | 40 | 30 | 38 | 22 | 52 | 44 | 42 | 55 |

Answer to Problem 3CGP
We can predict that at the 12 week a students speed will be between 55 and 60 word per minutes
Explanation of Solution
Given information:
The keyboarding speeds in word per minute (WPM) of 12 students is given below:
Experience(Weeks) | 4 | 7 | 8 | 1 | 6 | 3 | 5 | 2 | 9 | 6 | 7 | 10 |
Speed(WPM) | 38 | 46 | 48 | 20 | 40 | 30 | 38 | 22 | 52 | 44 | 42 | 55 |
Calculation:
Let the x-axis be the experience in weeks and y-axis be the Speed.
Now graph ordered pairs (seasons, field goals) as shown below:
As we can see from the
