Using the degrees of freedom (df) determined above and the 0.05 significance level, look up the critical χ2 value on a Table of Chi-Square Probabilities (an abbreviated version of this table, up to df=10, is given below).

What critical value t* should you use? In Table B, we consult the row corresponding to df = n − 1 = 11. We move across that row to the entry that is directly above 95% confidence level on the bottom of the chart. The desired critical value is t* = 2.201. Notice that the corresponding standard Normal critical value for 95% confidence is z* = 1.96.

M&M Statistics/A Chi Square Analysis. Introduction. ... Once we have calculated a value for the Chi-Square, we will compare it to a table of critical values. If the calculated Chi-Square value is smaller than the critical value, we ACCEPT our null hypothesis because our data is consistent with what we would expect—any slight difference is due ...

The computed statistic is t = -1.07 but the critical value from t-table = 2.131. Conclusion: There is no reason to reject that = 12.5. Question for you: Given the same sampling information perform the test H0: = 11 vs 11 at = .01.

Compare the t. crit (t-critical) value to the t obs. value. If the calculated t-value is greater than the appropriate critical t-value, this indicates that the means of the two samples are significantly different at the probability value listed (in this case, 0.05).

Step 3 Compute critical values and formulate decision rule. Critical value must be t, at 0.05 level of significance and 10 degrees of freedom; n1+ n2 -2 = 5 + 7 -2 = 10. =TINV(0.05,10) = + 2.23. Decision rule: Reject the null hypothesis if t-test from the sample data is larger than 2.23 or smaller than -2.23.

Find the critical value for 22 degrees of freedom when = 0.05 and the test is two-tailed. After the degrees of freedom reach 30, the table only gives values for multiples of 10. When the exact degrees of freedom are not specified in the table, the closest smaller value should be used. Test Statistic. Variance or St. Deviation
