For this week's discussion, please answer the following questions:

Suppose you are planning to sample cat owners to determine the average number of cans of cat food they purchase monthly. The following standards have been set: a confidence level of 99 percent and an error of less than five units. Past research has indicated that the standard deviation should be 6 units. What is the required sample size?

Once you have the solved the problem using an error of five units, reduce the error to 1 and recalculate the sample size. Do you notice any differences between two calculations? Why or why not? Please show the work and comment on your results.
