The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.5 days and a standard deviation of 2.3 days. What is the probability of spending more than 4 days in recovery? (Round your answer to four decimal places.)

And we can find this probability with the complement rule and with the normal standard table and we got:

Step-by-step explanation:

Let X the random variable that represent the patient recovery time of a population, and for this case we know the distribution for X is given by:

Where and

We are interested on this probability

And we can solve this problem using the z score formula given by:

And using this formula we got:

And we can find this probability with the complement rule and with the normal standard table and we got:

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
