Answer each of the following questions. You will need to use technology. Test the claim that there is a correlation between the explanatory variable, budget, and the response variable, Domestic Gross, at the 5% significance level. H0: p= 0 Ha: p≠ 0 p-value = (Rounded to exactly four decimal places.) Linear correlation coefficient r= (Round to exactly four decimal places.) Based on your work, is there a linear correlation? (Enter Y for yes or N for no) Compute the linear regression line in the form y=mx+b. (Round both m and b to exactly two decimal places.) y = ______ x + _______ Based on your work, does the regression model or the mean of the data serve as a better predictor of the Domestic Gross (in millions of $) based on a $13.2 million budget? Enter R for regression model, enter M for mean.)
A sample of 30 movies, an Excel .XLSX file of data is attached. Use the data contained to answer all parts of this question.
- The Movie column provides the name of the movie.
- The Year column provides the year the movies was released
- The Budget column provides the amount of money spent (in Millions of dollars) to film the movie
- The Domestic Gross($M) column provides the amount of money (in Millions of dollars) a movie made within the United States of America
