ne average age of doctors in a certain hospital is 43,0 years old. Suppose the distribution of ages s normal and has a standard deviation of 8.0 years. If 25 doctors are chosen at random for a committee, find the probability that the average age of those doctors is less than 43.8 years. Assume that the variable is normally distributed [6 marks) 14. A mandatory competency test for high school students has a normal distribution with a mean of 400...

Question 5 The waiting time in the emergency department in a large hospital is a concern for the outdoor patients. Based on the historical records of the hospital, it is found that the mean and standard deviation of waiting time of patients in the emergency department are 40 minutes and 6 minutes respectively. Assume that the distribution of waiting time follows a normal model. For the waiting time of a random sample of 25 patients from the population of patients...

1. Doctors obtained the data below on the number of recovery days in the hospital using the new and old appendix surgery procedures. Using the new and old surgery procedures, do the data provide sufficient evidence to conclude that the mean number of recovery days in the hospital is smaller with the new surgery procedure than with the old procedure? Use the appropriate statistical test to determine if the using new surgery procedure results in a smaller mean number of...
