[AI-generated answer — Bot GPT 3.5]

Given that P(z > a) = 0.7422, we need to find the value of a.

Using the standard normal distribution table, we can find the z-score corresponding to this probability of 0.7422.

Looking up the value in the z-table, we find that a z-score of approximately 0.63 corresponds to a probability of 0.7422.

Therefore, the answer is closest to option D) 0.68.
