In this test you will conduct and interpret T-tests using hypothesis testing and the SPSS program.
Students will follow the hypothesis testing steps for each problem. They will compute the problem using the SPSS program. They will write the results in appropriate APA format and interpret the results. Steps of hypothesis testing will be typed out in a word document, as well as a copy and paste of the SPSS output.
For the following problems, you will:
* Do all steps of hypothesis testing
* Write out the hypotheses
* Write out the steps you would do to calculate t
* Choose the t-cutoff score
* Calculate the t-statistic using the computer program SPSS, include effect size
* Write the t-statistic using proper APA format
* Decide whether or not you would reject the null hypothesis
* Interpret this result
* Be sure to include a copy of the SPSS output in the word document
1. Single Sample T-Test: A researcher would like to study the effect of alcohol on reaction time. It is known that under regular circumstances the distribution of reaction times is normal with $$\mu = 195$$. A sample of 15 subjects is obtained. Reaction time is measured for each individual after consumption of alcohol. Their reaction times were: 210, 216, 211, 240, 217, 219, 221, 222, 222, 227, 228, 223, 230, 228, and 232. Use $$\alpha = 0.05$$.
