Using the data attached, perform the following:
Imagine that you have population data with an average height of 5 feet 10 inches. Conduct a one-sample t-test to determine whether your sample population is significantly different from the general population.
Imagine that you have population data with an average satisfaction with a job score of 5. Conduct a one-sample t-test to determine whether your sample population is significantly more or less satisfied than the general population.
- Be sure to use the proper df and provide all the steps of calculations.
- Include an explanation of how you arrived at the critical value. Interpret the results using statistical analysis.
- With the analysis and results, explain whether you can conclude that your sample is taller or shorter than the general population.
- Describe how the results would be altered if you had twice as many subjects.
This solution is comprised of a detailed explanation of one sample t-test. This solution mainly discussed the question in which we defined null and alternative hypothesis, calculating the test statistics and p-value and provided the decision about the null hypothesis. Full calculations are shown for one sample t-test.
