Question 6 (1 point)

Answer 1

Answer:

c. 7.81

Explanation:

The critical value of a chi square represent a level at which the calculated chi square value can be compared. If the calculated chi square value is above the critical level value, it means the outcome of an experiment does not fit into the expected model.  On the other hand, if the the calculated chi square value is less than the critical value, it means the result fits into the expected model.

From the result in the table:

Degree of freedom = 4-1 = 3

At 0.05 probability level, the critical value of the chi square (from the table of critical chi square value) is 7.81.
