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!!

menu of the TI-83 or Ints menu of the TI-89. Therefore we never need to compute inverse t or critical t on its own. However, you would need to find critical t in the classical http://www.tc3.edu/instruct/sbrown/ti83/tcrit.htm approach to hypothesis test, for determining sample size, or for other applications. This note explains how to do it on the TI-83, TI-84, or TI-89. For all three models, let's assume that you want a 95% confidence interval with a sample size of 28. df= n−1= 27, and the area in one tail is (100%−5%)÷2= 2.5% or 0.025, so you how to need t(27,0.025). Contents: Notation TI-89Procedure TI-84Procedure TI-83Procedure Example:Inverset Example:Criticalt Example:MarginofError Notation t(df, rtail) is concerned with the t distribution for df degrees of freedom (df= n−1). It is the t value such that the area in the right-hand tail is rtail. This t value is also known as critical t. Caution: Some textbooks write the t function the other way, t(rtail,df). how to find Since df is a whole number and rtail is a decimal between 0 and 1, you will be able to adapt. TI-89 Procedure Method 1: Fill in the Blanks The flash application, Stats/List Editor, can compute critical t for any α/2 and df directly: Press [F5] [2] [2] for inverse t. In the "area" box, enter the area of the left-hand tail. For example, if you're finding t(27,0.025), the right-hand tail is 0.025 and the left-hand tail is 1−0.025. Enter the degrees of freedom (27), and press the [ENTER] key. Answer: t(27,0.025)= 2.0518 Try this method with the examples below. Method 2: Function You can also find critical t right on the main screen by using the invT function. This is particularly handy when you intend to use the number in further calculations. The function format is TIStat.inv_t(ltail,df). Here's the procedure: Press [CATALOG] [F3] [plain9 makes I] [ENTER] for TIStat.inv_t(. Enter the area of the left-hand tail. Since 0.025 is the right-hand tail, 1−0.025 is the left-hand tail. Press the comma and enter the degrees of freedom, 27.
