To find the table value for a right-tailed area in the chi-square distribution, you need to refer to the chi-square distribution table. These tables provide critical values for different degrees of freedom and different levels of significance.
In this case, we are given a right-tailed area of 0.05 and 8 degrees of freedom. To find the table value, look for the row corresponding to 8 degrees of freedom and locate the column that is closest to the given area of 0.05.
From the options provided, the closest value to 0.05 in the table is 0.05. The corresponding table value for 8 degrees of freedom is 11.07.
Therefore, the answer is A) 11.07.
