The t-distribution is “flatter” and has “heavier tails” than the N(0,1) distribution. As the sample size increases, the t-distribution approaches the N(0,1) distribution. Example. Find the critical t value for =0.05 with d.f. = 16 for a right-tailed t test. Solution. Find the 0.05 column in the top row and 16 in the left-hand column. ................
