Choice 2 9.2853 Step 9 - Confidence Intervals for the Average Relative Skill of All Teams in the Assigned Team's Years The management also wants to you to calculate a 95% condence interval for the average relative skill of all teams in the years 1995-1998. Calculate this confidence interval. You are to write this code block yourself. Use Step 3 to help you write this code block. Here is some information that will help you write this code block. Reach out to your instructor if you need help. 1. The dataframe for the years 1995-1993 is called assigned _years_league_df 2. The variable 'elo_u1 represents the relative skill of teams. 3. Start by calculating the mean and the standard deviation of relative skill [ELO) in years 1996-1993. Calculate 11 that represents the sample size. Calculate the standard error which is equal to the standard deviation of Relative Skill (ELO) divided by the square root of the sample size n. 6. Assuming that the population standard deviation is known, use Python methods for the Normal distribution to calculate the condence interval. '7. Your statistics should be rounded to two decimal places. 91:\
