A relative skill level of 1420 represents a critically low skill level in the league. The management of your team has hypothesized that the average relative skill level of your team in the years 2013-2015 is greater than 1420. Test this claim using a 5% level of significance. For this test, assume that the population standard deviation for relative skill level is unknown Make the following edits to the code block below. 1. Replace ??DATAFRAME_YOUR TEAM?? with the name of your team's dalaframe. See Step 2 for the name of your team's dataframe.
2. Replace ??RELATIVE_SKILL?? with the name of the variable for relative skill see the table included in the 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
3. Replace ??NULL HYPOTHESIS VALUE?? with the mean value of the relative skill under the null hypothesis.
