Suppose the amount of time a doctor spends with their patients is normally distributed with a mean of 17.4 minutes and with standard deviation of 3.8 minutes. Suppose 26 patients have scheduled appointments on one day. What is the probability that the mean amount of time for those 26 patients is less than 18.5 minutes, which would be equivalent to the doctor seeing patients for 8 hours and 1 minute that day.
1. The time it takes for patients to be released from emergency room in a hospital follows normal distribution with an average of 2 hours and standard deviation of 12 minutes. a) What is the probability that a patient being released before 1 hour and 48 minutes? 2- Ages of students in a class are distributed normally distributed with the min age at 17 and max at 32 a) What percent of students are older than 22?
A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 19 minutes. How large a sample should she take to estimate the mean time to within 5 minutes with 92% confidence? Sample size=

6) A medical researcher wants to investigate the amount of time it takes for patients' headache to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 20 minutes. How large a sample should she take to estimate the mean time to within 1 minute with 90% confidence? Page 2 of 2

If a study shows that the amount of time a student sleeps on any given nights is normally distributed with a mean of 7.2 hours and a standard deviation of 3 hours. Find the probability of 28 randomly selected students sleeping less than 8 hours.
3. The time needed to complete a final examination is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes. Answer the following questions. a. What is the probability of completing the exam in one hour or less? b. What is the probability that a student will complete the exam in more than 60 minutes but less than 75 minutes (i.e., between 60 and 75 minutes)? c. What is the longest time in minutes it...
The amount of time that you have to wait before seeing the doctor in the doctor's office is normally distributed with a mean of 15.2 minutes and a standard deviation of 15.2 minutes. If you take a random sample of 64 patients, what is the probability that the average wait time is greater than 20 minutes?
