Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Textbook Question

Chapter 6, Problem 6RE

Emergency Room Visits The probability that a randomly selected patient who visits the emergency room (ER) will die within 1 year of the visit is 0.05.

Source: SuperFreakonomics

a. What is the probability that exactly 1 of 10 randomly selected visitors to the ER will die within 1 year? Interpret this result.
b. What is the probability that fewer than 2 of 25 randomly selected visitors to the ER will die within 1 year? Interpret this result.
c. What is the probability that at least 2 of 25 randomly selected visitors to the ER will die within 1 year? Interpret this result.
d. What is the probability that at least 8 of 10 randomly selected visitors to the ER will not die within 1 year?
e. Would it be unusual if more than 3 of 30 randomly selected visitors to the ER died within 1 year? Why?
f. In a random sample of 1000 visitors to the ER, how many visitors are expected to die within the next year? What is the standard deviation number of deaths?
g. At a particular emergency room, a researcher obtains a random sample of 800 visitors and finds that after 1 year 51 of them have died. Do you think this particular emergency room should be investigated to see if something unusual is occurring?
