Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. Another law will be endorsed to expand the uniformity between the specialists. The public authority chose to cause everybody to have a similar occupation classification by playing out the accompanying activity quite a few times (conceivably zero). There is a decent objective boundary k=ab depicting that it is so natural to persuade people in general, and it will be utilized to decide the accomplishment of an activity. In an activity, the public authority initially chooses a task class x with something like one laborer at the current second. Assume i1,… ,im (i1<… <im) are the places of the multitude of laborers with work classification x. In the event that k⋅(im−i1+1)≤m, the public authority can pick any work classification y with no less than one specialist at the current second and change the work class of all laborers with work class x to work classification y.

Step 4: Hypothesis Test for the Population Mean (II) A team averaging 110 points is likely to do very well during the regular season. The coach of your team has hypothesized that your team scored at an average of less than 110 points in the years 2013-2015. Test this claim at a 1% level of significance. For this test, assume that the population standard deviation for relative skill level is unknown. 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 your team is called your_team_df. 2. The variable 'pts' represents the points scored by your team. 3. Calculate and print the mean points scored by your team during the years you picked. 4. Identify the mean score under the null hypothesis. You only have to identify this value and do not have to print it. (Hint: this is given in the problem statement) Assuming the…
