- Use the data in the table below for the following 4 problems. For each, use the stated µ and s to calculate the z score, get the p value (3 decimal places), and write out a formal APA statement of conclusion for each child. When you are finished with that, then answer the following question for each pair of parameters: Which child or children, if any, appeared to come from a significantly different population than the one used in the null hypothesis? What happens to the “significance” of each child’s data as the data are progressively more dispersed?
- NOTE: Problems #1 and #2 are PRACTICE PROBLEMS with the answers available via the link beside them.
- Problems #3 and #4 are GRADED PROBLEMS
- Please submit all 4 problems using the Module 3 Assignment 1 Template found in the Doc Sharing area.
- Problem 1. µ = 100 seconds and s = 10 (practice problem – link to answer)
- Problem 2. µ = 100 seconds and s = 20 (practice problem – link to answer)
- Problem 3. µ = 100 seconds and s = 30 (graded problem)
- Problem 4. µ = 100 seconds and s = 40 (graded problem)
- Given the research scenario, data points, set of population parameters and alpha set at p = .05, is the student able to generate the correct:
- Pair of hypotheses for each data point
- A z statistic and p value for each data point
- Decision about the null hypothesis for each data point
- APA-formatted statement of results for each data point
- Module 3 Assignment 1 Template
- Fill in the answers for each table and answer the concluding FOUR questions below. Please round up your z scores to the hundredths spot, two decimals to the right and p values to the thousandths spot three decimals to the right as needed. If the p value is less than .001, please report p < .001. Please note when a value appears in SPSS as .000, it is truly p<.001. If you click on the .000 in the SPSS output you can see the value.
- Make sure to write out a formal APA statement of conclusion for each child as the instructions state.
