Chi Square Table Degrees Of Freedom. Thus according to the chi square distribution table the critical value of the test is 5 991. Or just use the chi square calculator.
If the test statistic is greater than the upper tail critical value or less than the lower tail critical value we reject the null hypothesis. Therefore option d is correct. But it may not be immediately clear why this is the correct number of degrees of freedom.
To find probability for given degrees of freedom read across the below row until you find the.
Df r 1 c 1 df 3 1 4 1 df 6 d f r 1 c 1 d f 3 1 4 1 d f 6. The resulting figure is the degrees of freedom for the chi square test. But it may not be immediately clear why this is the correct number of degrees of freedom. Thus as the sample size for a hypothesis test increases the distribution of the test statistic approaches a normal distribution.
