Question

Recent legal changes to marijuana laws have altered the atmosphere in which people utilize the drug. Several states have legalized marijuana as a recreational drug. Below is ‘Hypothetical’ data on the percentage of users in both states that have (hypothetically) legalized marijuana and states that have not legalized marijuana. The government desires to know if the law is a deterrent to using the drug and hires you to figure it out. Examine the data and figure out the following questions below.

18. What is the pooled variance?

19. Compute the appropriate statistic?


20. Discuss the findings at p<.05 (same as the 95% level)?

Answer 1

18. The pooled variance is the weighted average of the variances of two or more groups. However, the data provided in the table does not include information on variances or multiple groups, so it is not possible to calculate the pooled variance.

19. It is not clear what specific statistic is being asked to be computed. Depending on the research question, different statistics could be calculated, such as mean, median, standard deviation, or correlation coefficient.

20. It is not possible to discuss findings at p<.05 (same as the 95% level) without additional information on the research question and the specific statistic being analyzed. In general, a p-value of less than .05 indicates that there is a statistically significant difference between groups or variables, indicating that the observed difference is unlikely to be due to chance. However, without more information on the research question and the specific statistic being analyzed, it is not possible to draw conclusions or discuss findings at this level of significance.
