Hi

I got a bit confused on my conclusion.

the Jupyter script is as follows:

Step 6: Hypothesis Test for the Difference Between Two Population Means

The management of your team wants to compare the team with the assigned team (the Bulls in 1996-1998). They claim that the skill level of your team in 2013-2015 is the same as the skill level of the Bulls in 1996 to 1998. In other words, the mean relative skill level of your team in 2013 to 2015 is the same as the mean relative skill level of the Bulls in 1996-1998. Test this claim using a 1% level of significance. Assume that the population standard deviation is unknown. Make the following edits to the code block below:

1. Replace ??DATAFRAME_ASSIGNED_TEAM?? with the name of assigned team's dataframe. See Step 1 for the name of assigned team's dataframe.
2. Replace ??DATAFRAME_YOUR_TEAM?? with the name of your team's dataframe. See Step 2 for the name of your team's dataframe.
3. Replace ??RELATIVE_SKILL?? with the name of the variable for relative skill. See the table included in Project Two instructions above to pick the variable name. Enclose this variable in single quotes. For example, if the variable name is var2 then replace ??RELATIVE_SKILL?? with 'var2'.

After you are done with your edits, click the block of code below and hit the Run button above.

In[6]:

import scipy.stats as st mean_elo_n_project_team = assigned_team_df['elo_n'].mean() print("Mean Relative Skill of the assigned team in the years 1996 to 1998 =", round(mean_elo_n_project_team,2)) mean_elo_n_your_team = your_team_df['elo_n'].mean() print("Mean Relative Skill of your team in the years 2013 to 2015 =", round(mean_elo_n_your_team,2)) # Hypothesis Test # ---- TODO: make your edits here ---- test_statistic, p_value = st.ttest_ind(assigned_team_df['elo_n'], your_team_df['elo_n']) print("Hypothesis Test for the Difference Between Two Population Means") print("Test Statistic =", round(test_statistic,2)) print("P-value =", round(p_value,4))

Mean Relative Skill of the assigned team in the years 1996 to 1998 = 1739.8

Mean Relative Skill of your team in the years 2013 to 2015 = 1427.57

Hypothesis Test for the Difference Between Two Population Means Test Statistic = 44.72

P-value = 0.0

from the above information I have to write a conclusion and the questions are as follows:

Conclusion

Describe the results of your statistical analyses clearly, using proper descriptions of statistical terms and concepts.

• What is the practical importance of the analyses that were performed?
• Describe what these results mean for the scenario.
