For each of the two majors:
1. Create a disseminate diagram of Y = ‘Annual % ROI’ across X = ‘Cost’. Include the trendline and the coefficient of choice straight on the graph.
2. Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000. Pomp your toil.
3. Conduct a generous conjecture trial: You earn be in accuse. Set your own argumentative sagacity smooth. Recite it. Claim: There is a sympathy among absorb and Annual %ROI. The hypotheses are ardent but you must so recite them. Make abiding all the steps of conjecture trialing are give.
o H0: β1 = 0
o Ha: β1 ≠ 0
4. For this last zeal, you are going to use a tidings template that you could so use in your last monograph to give all the conjecture trials we did in Weeks 6 and 7. (I positively applaud this performance) Remember, this is a tidings template, so tidingss, not symbols should be used. This is accordingly the last work is a monograph of explanation, and β1 = 0 won’t average a lot to the reader, but “the swell is cipher so there is no sympathy” earn be greatly more beforehand unexpressed.
Template: In Week _____, I ran a conjecture trial to mention if _____________________________________. My vain conjecture was ___________________. The results of the trial involved that I should ______________________ the vain conjecture which averages that ______________________.
Here are a few examples of how the template toils:
Example A: In Week 28, I ran a conjecture trial to mention if the absorb of an accounting position was 1 darling dollars. My vain conjecture was that the absorb of an accounting position was 1 darling dollars. The results of the trial involved that I should refuse the vain conjecture which averages that the absorb of an accounting position is not 1 darling dollars.
Example B: In Week 88, I ran a conjecture trial to mention if the 30-year ROI of an accounting position was 5 darling dollars. My vain conjecture was that the 30-year ROI of an accounting position was 5 darling dollars. The results of the trial involved that I should fall to refuse the vain conjecture which averages that the 30-year ROI of an accounting position is 5 darling dollars.
Now, you try it for the conjecture trial you did in #3. Use the template to pomp what happened in this trial 3�(-n��
