I'm just trying to figure out how to calculate those two figures with the calculator in this particular problem (since my online math class doesn't provide instructions for calculators): Assume you plan to construct a 95% confidence interval. Number of applications in sample: In 2003: 42 Current Year: 33 Number of online applications in sample: In 2003: 14 Current Year: 18 I'm thinking it's supposed to be set up like an n1, x1, n2, x2 type problem but when I used the 2PropZtest it didn't give the margin of error. Would anyone happen to know how to calculate the margin of error and the 95% confidence interval? I know the answers because of my class's walkthrough, but it doesn't describe how to arrive at the answers on a calculator, it just says "use technology." Any help is appreciated, thanks!!

Rumsey When a research question asks you to find a statistical sample mean (or average), you need how to to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean (assuming a certain condition is met -- see below) is is the population standard deviation, n is the sample size, and z* is the appropriate z*-value for your desired level of confidence (which you can find in the following table). z*-Values for Selected (Percentage) Confidence Levels Percentage Confidence z*-Value 80 1.28 how to find 90 1.645 95 1.96 98 2.33 99 2.58 Note that these values are taken from the standard normal (Z-) distribution. The area between each z* value and the negative of that z* value is the confidence percentage (approximately). For example, the area between z*=1.28 and z=-1.28 is approximately 0.80. This chart can be expanded to other confidence percentages as well. The chart shows only the confidence percentages most commonly used. Here are the steps for calculating the margin of error for a sample mean: Find the population standard deviation and the sample size, n. The population standard deviation, will be given in the problem. Divide the population standard deviation by the square root of the sample size. gives you the standard error. Multiply by the appropriate z*-value (refer to the above table). For example, the z*-value is 1.96 if you want to be about 95% confident. The condition you need to meet in order to use a z*-value in the margin of error formula for a sample mean is either: 1) The original population has a normal distribution to start with, or 2) The sample size is large enough so the normal distribution can be used (that is, the Central Limit Theorem applies ). In general, the sample size, n, should be above about 30 in order for the Central Limit Theorem to
