Using the incorrect critical value from the t-distribution for a given sample size (N) affects the probability of making a Type I error, which is rejecting a true null hypothesis (H0). The correct critical value ensures that this probability is equal to the significance level (α). Using an incorrect value means the actual probability of making a Type I error will not match the intended α, hence option D is correct.
