1. Run the regression analysis (Include all options). Report the least squares regression line. Give the 95% confidence interval for the least squares estimate of the slope. Report the correlation coefficient. Interpret. Report the coefficient of determination. Interpret. and Use the ANOVA output and write out the hypothesis being tested, the test statistic, the critical value, p-value, and fully write out the conclusion.

In Major League Baseball, the American League (AL) allows a designated hitter (DH) to bat in place of the pitcher, but in the National League (NL), the pitcher has to bat. However, when an AL team is the visiting team for a game against an NL team, the AL team must abide by the home team’s rules, and thus, the pitcher must bat. A researcher is curious if an AL team would score more runs for games in which the DH was used. She samples 20 games for an AL team for which the DH was used, and 20 games for which there was no DH. The data are below. The population standard deviation for runs scored is known to be 2.49 for both groups. Assume the populations are normally distributed. DH no DH 0 3 8 6 10 2 2 4 3 0 4 5 7 7 8 6 6 1 5 8 1 12 1 4 5 6 4 3 4 4 3 0 8 5 11 2 11 1 0 4 Is there evidence to suggest that more runs are scored in games for which the DH is used? Use α=0.10.

A randomised controlled trial was conducted to assess the effectiveness of a new eye drop to reduce eye pain in patients suffering from a systemic condition affecting both eyes. Each patient received the prescribed dose of the new eye drop in one eye and the same dose of an existing drop in the other eye. The investigators randomised which eye was treated with the new eye drop and which received the existing eye drop. 45 patients were asked to rate the level of pain in each eye on a 0–10 scale with higher scores indicating higher levels of pain.The dataset is provided below.The dataset contains the following variables.
• ID: Participant ID number
• Pain_ctl = pain score in the eye receiving the existing drop
• Pain_new = pain score in the eye receiving the new drop
a) What are the study factor and the outcome factor?
b) State the null hypothesis and alternative hypothesis for the study.
c) Which statistical test would be appropriate to test the null hypothesis you have stated and why?
d) Use Stata to conduct the statistical test you stated in part (e) report the key findings and interpret them.Report all the relevant statistics and graphs required for checking the assumptions with interpretations
e) Write a brief report summarising all the results you have obtained and state your conclusion.

The language is C++
Below are a list of sequences of numbers. Your job is to program each sequence with any loop of your preference (while, for, do/while). I want the code to output the sequence provided and the next number in the sequence (you can output more but there is 1 sequence that may only have 1 number after).. Please order and notate each sequence in your output –. The output should also be horizontal like that shown below (if you output it vertically it will be -10pts). Each sequence should be programed with only 1 loop and optionally 1 selection statement. Hint: a selection statement may be used for the last 3 problems.
