Place the ' value for your sample in the proper column (under the appropriate P value) of the table on the chalkboard that is prepared in the style of Table 3.4. nd hc Yarious Class Members for Individual Samples Removed

Explanation / Answer

1.
Degrees of freedom = 2 - 1 = 1

2.
chi-square = 0.2688

3.
probability = 0.6041

4.
The probability value calculated from the chi-square = 0.2688, is not less than the singnificance level of 0.05. Hence do not reject the null hypothesis.

Classes Observed(O) Expected€ (O-E) (O-E)^2 (O-E)^2/E colored 49 46.5 2.5 6.25 0.1344 white 44 46.5 -2.5 6.25 0.1344 total 93 0.2688
