  • a Slides 15 and 21 were hybridized with cDNAs from one set of reverse transcriptions; slides 35 and 45 were hybridized with cDNAs from the second set of reverse transcriptions.

  • b Two-tailed t test of H0: μ1 − μ2 = 0; df = 2(n − 1) = 108 .

  • c The critical value of t0.05[108] = 1.982 and t0.9[108] = 0.126 .
