c?

The patient recovery time for a particular surgical procedure is normally distributed with a mean of 6.4 days and a standard deviation of 2.3 days. and a) The middle 95% of patients have a recovery time between b) Compute the probability for a patient having a recovery time more than 12 days. Write the mathematical probability statement. c) If X is the recovery time, compute P (4 < x < 5.5) and interpret what it means in the context of the problem. d) Compute the z-score for a patient who takes 9 days to recover, and interpret what it means in the context of the problem. e) Compute the patient recovery time for a particular surgical procedure that is at the 75th percentile.
