To test: The claim that there is a difference between proportions of that there will be an increase in gamification and significant increase in gamification.
Answer to Problem 74E
Solution: There is a difference between proportions.
Explanation of Solution
Calculation: The null and alternative hypotheses are
People who think that there will be no increase in gamification can be calculated as follows:
People who think that there will be a significant increase in gamification can be calculated as follows:
To test the significance, Minitab software is used. The steps to be followed are provided below:
Step 1: Enter the data in the Minitab worksheet.
Step 2: Go to Stat
Step 3: Select summarized data.
Step 4: Click on “option” button and choose significance level and alternative hypothesis.
Step 5: Select “Use test and interval based on
Step 6: Click on OK.
Hence, the obtained z- score is
Conclusion: Since the p-value is 0.000, which is less than 0.05, the null hypothesis is rejected at 5% level of significance. It can be concluded that there is a difference between proportions of the result that states whether or not there will be an increase in gamification in the future.
