Researchers are conducting anonpooled,left-tailed two-mean hypothesis test at a 1% significance level. The two samples have sizes n1=17 and n2=11. The samples have standard deviations of s1=7 and s2=3. The researchers compute the degrees of freedom, shown in the following calculation.

The next step for the researchers is to find the critical value(s) for the hypothesis test. Determine the critical value(s) for this test.
