For this problem:
- What type of test and why did I choose this specific test?Answer here Check your assumptions to be sure that you can use this statistic!
- Write the Null and alternative hypotheses.
- What is the obtained statistical value and the critical value?
- Is it significant, how do you know?
- Do I reject my null?
- Write the sentence and (APA) statistics format for these results. When it says (APA) format it has to be statistically and tutors are welcome to write their APA format conclusion
