A production supervisor at a major chemical company must determine whether the variance of the chemical yield of two catalysts XA-100 or catalyst ZB-200, differs significantly. The supervisor collected 5 observations of XA-100 yields and 7 observations of ZB-200 yields. The sample variance is 0.27 for XA-100 and 1.23 for ZB- 200. If we wish to show that the variance difference is significant at the .10 level of significance, what is the correct critical value to use?
