... under the t-distribution with 8 degrees of freedom for the value that the T statistic would take at that confidence and find it is 2.306 (see table). Our T statistic exceeds this and thus the mean of the mutant sample is different from the mean of the normal sample at 5% significance. So our gene is ...

... Example: Finding Critical Values for t Find the critical value t0 for a left-tailed test given = 0.05 and n = 15. Solution: • The degrees of freedom are d.f. = n – 1 = 15 – 1 = 14. • Look at α = 0.05 in the “One Tail, ” column. • Because the test is lefttailed, the critical value is negative. L ...
