uppose at a pulmonologist’s office the mean age of patients was 50 years of age with a standard deviation of 9 years. Assume patient ages are approximately normally distributed. We pull 25 records randomly and note the age of patients at a Pulmonologist’s office. The ages are as follows: 38, 41, 53, 52, 50, 49, 43, 21, 29, 39, 82, 74, 73, 60, 61, 56, 56, 53, 51, 50, 48, 49, 56, 56, 55 (a) Find the mean, median, and modal age of a patient in the records pulled. (b) Compute a Five-Number Summary of the data. Find any outliers. (c) Make a boxplot of the data.
1. Suppose at a pulmonologist’s office the
38, 41, 53, 52, 50, 49, 43, 21, 29, 39, 82, 74, 73, 60, 61, 56, 56, 53, 51, 50, 48, 49, 56, 56, 55
(a) Find the mean,
(b) Compute a Five-Number Summary of the data. Find any outliers.
(c) Make a boxplot of the data.
(d) What is the probability that a random sample 25 has this mean(part a) or greater?
(e) Find the probability that random sample of 25 records has a mean age of 53 or greater.
(f) Find the probability that a random sample of 25 records has a mean age between 49 and 51.
