Question

CramX · Accepted Answer

Step 1: : First, you need to calculate the standard deviation (s) and the sample size (n) for your data set.. The formula for the standard deviation is: Step 2: : After calculating the standard deviation, you can now calculate the margin of error (E) using the following formula:. For a 95% confidence level, the z-score is approximately 1.96. Step 3: : To calculate the standard deviation and the margin of error on a TI-84 Plus CE calculator, follow these steps:. Step 4: . Press the STAT key and select 1-Var Statistics from the menu. Step 5: . Enter your data set into the calculator by pressing the ENTER key after each data point. Step 6: . After entering all data points, press the STAT key again and select Calculate from the menu. Step 7: . Step 8: . Now, press the STAT key and select Edit... from the menu. Step 9: . Enter the number of data points (n) in the L1 list and press ENTER. Step 10: . Press the STAT key and select Calculate from the menu. Step 11: . Choose n to display the sample size. Step 12: . Now, press the VARS key and select 2-nd 0 (Statistics) from the menu. Step 13: . Select 6 (z-score) and enter the desired confidence level (e.g., 1.96 for a 95% confidence level). Step 14: . Press the MATH key and select 5 (invNorm) from the menu. Step 15: . Enter the z-score and press ENTER to calculate the corresponding margin of error (E). Final Answer: After following the steps above, you will have calculated the margin of error (E) for your data set using a TI-84 Plus CE calculator.
