From eight days of tracking he compiled the following data: People (P) 11 10 |9 3 Cups of coffee (n) 1 2 445 Unless otherwise stated, you can round values to two decimal places. a) Using regression to find a linear equation for P(n) P(n) 13.125 – 1.757 b) Find the correlation coefficient -0.9482 c) Does the correlation coefficient indicate a strong linear trend, a weak lineer trend, or trend? strong linear trend Sweak linear trend KD no linear trend of the problemn d) Interpret the meaning of the slope of your formula in the conter For every one unit change in the number io cdffees taken 1.75less nunber ot people to cublein on the professor keep ing every other parameter corstant. e) interoret the meaning of the Fintercept in the context of the problem dépendeno varienle pet h44/4neree dndeter ASUS 近


Extracted text: d) Interpret the meaning of the slope of your formula in the context of the problem For every one unit change in the number of coffees taken 1.75 less number of people to complain on the professor keeping every other parameter constant. e) Interpret the meaning of the P intercept in the context of the problem dependent variable per unit increase independent variable. Slope b = -1.75 The model predicts that attitude of people wil1 decrease 1.75 for each additional cup of coffee. f) Use your model to predict the number of people that will complain about his attitude if he drinks 8 cups of coffee -0.875 g) Is the answer to partf reasonable? Why or why not? it is not reasonable be to predict the number of the people that will complain about attitude it he drinks 8 cup of coffee because drinking B kups of coffee is out of the given range. Thus, it is not reasonable to answer part f because h) How many cups of coffee should he drink so that no one will complain about his attitudeit is ok to round to one decimal place Question Help: Messate insTructor Submit Question ASUS 立
