Hi can you help me with 1 to number 6 please!!!!!!!   A study was done to look at the relationship between number of movies people watch at the theater each year and the number of books that they read each year. The results of the survey are shown below. Movies 8 1 0 8 9 2 1 8 1 4 9 Books 6 14 16 11 5 10 14 8 11 13 8  r2 =  ___________    (Round to two decimal places)    Interpret r2 : There is a large variation in the number books people read each year, but if you only look at people who watch a fixed number of movies each year, this variation on average is reduced by 69%. There is a 69% chance that the regression line will be a good predictor for the number of books people read based on the number of movies they watch each year. 69% of all people watch about the same number of movies as they read books each year. Given any fixed number of movies watched per year, 69% of the population reads the predicted number of books per year. The equation of the linear regression…

← The results of a survey on the belief that stem cell research has merit are shown in the table below. % X 1524 SEP 28 95% CI (0.7052, 0.7434) Here, X denotes the number who believed that stem cell research has merit. Complete parts a and b below. N 2104 a. Explain how to interpret "Sample p" and "95% CI" in this table. The "Sample p" is the proportion of all respondents in the sample who believe stem cell research has merit, 1524/2104 0.72. The "95% CI" is the 95% confidence interval and it means that we can be 95% confident that the interval 0.7052 to 0.7434 contains the population proportion. (Round to four decimal places as needed.) b. What is the 95% margin of error associated with the poll? The 95% margin of error is. (Round to four decimal places as needed.)
