To find the critical value of χ², we need to use the chi-square test for independence. The degrees of freedom for this test are calculated as (r-1)*(c-1), where r is the number of rows and c is the number of columns. In this case, we have 4 pediatricians and 2 categories (show and no-show), so r=4 and c=2. Therefore, the degrees of freedom are (4-1)*(2-1) = 3. Using a chi-square distribution table with a significance level of .10 and 3 degrees of freedom, we find the critical value to be 6.25, which is option B.
