The patient recovery time from a particular surgical procedure is normally distributed with a mean of 21 days and a standard deviation of 7.88 days. What is the probability that it will take less than 11 days to a randomly selected patient to recover from the surgical procedure? QUESTION 20 The patient recovery time from a particular surgical procedure is normally distributed with a mean of 16 days and a standard deviation of 2.55 days. Let X - is the number of days a randomly selected patient needs to recover from the surgical procedure What is the lower bound of 90% confidence interval of X?
