In swimming, clearly you would like to swim fast, but swimming consistent times is also important. A survey of 30 swims by men on a local university's swim team found a variance of their swimming times was 10. A similar survey of 41 swims by swimmers at a different university found the variance was 17. When testing the hypothesis (at the 10% level of significance) that the variances are equal, what is the critical value? (please round your answer to 2 decimal places)
