Final answer:
The central limit criteria are met for the time lapse between administration of the muscle relaxant and the beginning effects of the drug, allowing us to use the normal distribution to analyze the data.
Step-by-step explanation:
The central limit criteria are met for the time lapse between administration of the muscle relaxant and the beginning effects of the drug. The criteria state that the sample size should be greater than 30, which is satisfied since one patient is selected at random. Additionally, the population distribution should be approximately normal, which is also satisfied since the time lapse follows a normal distribution. Therefore, we can use the normal distribution to analyze the data.
