Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 52 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible?

Honda uses statistical process control to monitor and improve a variety of processes. Employees collect data, and then analyze it using statistical process control charts. They can make adjustments if needed. The statistical process control charts enable workers to understand precisely how processes are working and anticipate problems before they occur. One interesting use is in monitoring the effort required to close a door. Honda monitors the speed of the door required to make it latch by using a special...

A researcher uses an ANOVA to compare nine treatment conditions with a sample size of n = 13 in each treatment. For this analysis find the degrees of freedom. What is df(treatment)? This is sometimes referred to as the “numerator degrees of freedom.” What is df(error)? This is sometimes referred to as the “denominator degrees of freedom.” If the scenario was changed so that there were still nine treatments, but there were different sample sizes for each treatment (a.k.a. an...

A process has an in-control fraction nonconforming of p = 0.02. a) What sample size would be required for the fraction nonconforming control chart if it is desired to have a probability of a least one nonconforming unit in the sample to be at least 0.9? b) Now assume n = 200. Establish a control chart for the fraction nonconforming.
