When individuals in a sample of 150 were asked whether or not they supported capital punishment, the following information was obtained. The calculated test statistic is equal to 4.
First we have to get the expected value. The expected value based on its probability distribution, describes the long-term average level of a random variable.
We have Ei = ∑x/n
x = 150
n = 3
= 150 / 3
= 50
n = 3
Next is the test statistics
We would have to solve for (Oi-Ei) and (Oi-Ei)²
40 - 50 = -10, -10² = 100
60 - 50 = 10, 10² = 100
50 - 50 = 0, 0 ² = 0
Next we have to solve (Oi-Ei)²/Ei
100 / 50 = 2
100 / 50 = 2
0 / 50 = 0
The test statistic = 2 + 2 = 4
Hence we have that the calculated value of the test statistic from the sample is 4.
