## How To Find Sample Mean On Ti 84

Confidence intervals for the population mean Example 1: A sample of 38 items is chosen from a normally distributed population with a sample mean of 12.5 and a population standard deviation of 2.8.

- Using the TI-83/84 Plus Chapter 8: Hypothesis Testing - One Sample Here we see how to use the TI 83/84 to conduct hypothesis tests about proportions and means. The software will calculate the test statistic and the P-value for the test statistic. It does not give you the critical value. For tests about means, you can either input raw data via a list or simply enter the sample statistics. In
- On the TI-84 Plus, the randIntNoRep command does not have a wizard to help you. The syntax for the command is randIntNoRep(lower,upper). Unlike the TI-84 Plus C, you don’t have the option of adjusting the number of terms.
- Any easy way to calculate E on the ti-84? I can do it manually, but it's a lot of button mashing. I would assume/hope there is just a simple function that I can punch in a few values and have it do it for me.
- Complete the statement with an open curly bracket – the "{" sign – and the numbers for which you want to find the standard deviation, followed by a closing curly bracket and closing parenthesis. For example: stdDev({1,2,3,4,5,6}).
