Charlie gathered data about the time it takes him to complete a crossword puzzle and the number of clues in the puzzle. He used a graphing tool to organize the data in a scatter plot and find the line of best fit.
He found the relationship between the number of clues, x, and the time required to complete the puzzle, y, is modeled by the equation y = 0.376x + 15.48, and the correlation coefficient for the data is 0.219.
Could the line of best fit be used to make reliable predictions about the time it takes Charlie to complete a crossword puzzle? Yes, because the slope of the line of best fit is closer to 0 than 1. No because the slope of the line fits closer to 0 than 1. yes because of the correlation. No because the correlation. REWARDING 30 POINTS PLEASE HELP
