Step 1
Solution: Given data
x | dx=x-A=x-30 | dx2 |
32 | 2 | 4 |
20 | -10 | 100 |
25 | -5 | 25 |
52 | 22 | 484 |
16 | -14 | 196 |
21 | -9 | 81 |
28 | -2 | 4 |
35 | 5 | 25 |
23 | -7 | 49 |
41 | 11 | 121 |
46 | 16 | 256 |
17 | -13 | 169 |
23 | -7 | 49 |
27 | -3 | 9 |
11 | -19 | 361 |
60 | 30 | 900 |
--- | --- | --- |
∑x=477 | ∑(dx)=-3 | ∑(dx)2=2833 |
Mean ˉx=∑x/n
=477/16
=29.8125
ˉx=29.8125 is not an integer, use assumed mean method
A=30
