Question

After reviewing data from a sample, an inference can be made about the population. For example, Find a data set on the internet. Some suggested search terms: Free Data Sets, Medical Data Sets, Education Data Sets. Based on the trends and the history of your data set, make a claim. What kind of test (left, right, two tailed) would you have to complete? Show work

Find a data set on the internet. Some suggested search terms: Free Data Sets, Medical Data Sets, Education Data Sets.

1. Introduce your Data Set and Cite the Source.
2. What trends do you notice in your data set?
3. Based on the trends and the history of your data set, make a claim. What kind of test (left, right, two tailed) would you have to complete?
4. Explain the steps needed to complete the Hypothesis Test. What is needed? show calculation

Helpful hints

1. Choose hypothesis (H₀) and the alternative hypothesis (Hᵃ):

Null Hypothesis (H₀): mean and Alternative Hypothesis (Hᵃ): mean

Observation: Is it right or left tail?

2. Use the significance level (alpha)

3. Compute the test statistic, z-score (Z₀)

4. Find the critical value using the alpha from Step 2.

5.Interpreting the results of the hypothesis test I compare Step 3 to Step 4 to either Reject H₀ or Fail to Reject H₀.

6, Hypothesis rejected or not rejected? Why?
