Which of the following statements is true?1. The R³ (.e., R-squared) tells us the percentage of the variation in the dependent variable (cost) that is explained by variation inthe independent variable (activity)II. The R (.e.. R-squared) varies from 0% to 100%, and the lower the percentage, the better the fit of the data to a straight line.ONeither statement is true.Only statement I is true.Only statement II is tru.O Both statements are true.

In this case, we need to identify the true statement.

The amount of time adults spend watching television is closely monitored by firms because this helps to determine advertising pricing for commercials. Complete parts (a) through (d). (a) Do you think the variable "weekly time spent watching television" would be normally distributed? If not, what shape would you expect the variable to have? O A. The variable "weekly time spent watching television" is likely uniform, not normally distributed. O B. The variable "weekly time spent watching television" is likely skewed left, not normally distributed. O C. The variable "weekly time spent watching television" is likely normally distributed. O D. The variable "weekly time spent watching television" is likely skewed right, not normally distributed. O E. The variable "weekly time spent watching television" is likely symmetric, but not normally distributed. (b) According to a certain survey, adults spend 2.45 hours per day watching television on a weekday. Assume that the standard deviation for…
2. You are president of the high school band booster club. You have arranged for school's jazz band to perform at a local coffee shop for three hours. In exchance the performance, the booster club will receive three-quarters of the shop's gross receint during that three-hour period. a. Let r be the independent variable representing the gross receipts of the coffee shon during the performance. Let y be the dependent variable representing the share of the gross receipts that the coffee shop will donate to the band boosters. Write an equation relating r and y. b. Use the equation from part a to complete the following table. x, TOTAL GROSS RECEIPTS ($) 250 500 750 1000 y, BOOSTERS' SHARE ($) c. If the coffee shop presents you with a check for $650, what were the gross recepo during the performance? Estimate your answer using a numerical approach.
What is the relationship between the amount of time statistics students study per week and their final exam scores? The results of the survey are shown below. Time 6 1 16 12 2 1 16 1 Score 72 51 87 72 60 63 100 48 r2r2 = (Round to two decimal places) There is a large variation in the final exam scores that students receive, but if you only look at students who spend a fixed amount of time studying per week, this variation on average is reduced by 84%. There is a 84% chance that the regression line will be a good predictor for the final exam score based on the time spent studying. Given any group that spends a fixed amount of time studying per week, 84% of all of those students will receive the predicted score on the final exam. 84% of all students will receive the average score on the final exam. 3. Use the model to predict the final exam score for a student who spends 11 hours per week studying.Final exam score = (Please round your answer to the nearest whole…
