\(\chi^{2}\) test statistics=____

Short Answer

Expert verified

The value of test statistics is \(10301.85\).

Step by step solution

01

Step 1. Given information

Given table-

02

Step 2. Calculation

The formula to calculate the test statistics is Test Statistics \(=\sum \frac{(O-E)^{2}}{E}\)

To use the formula \(=(B3-B11)*(B3-B11)/B11\) in the cell \(B18\) and drag the same formula to cell \(B21\) .After that, take the total of columns and total of rows.

Test Statistics \(=\sum \frac{(O-E)^{2}}{E}\)

\(=1523.088+169.0517+4505.49+948.6876+3155.531)\) or \(4970.562+901.76+2382.545+2046.981)\)

\(=10301.85\)

Therefore, the value of test statistics is \(10301.85\).
