particular professor has noticed that the number of people, P, who complain about his attitude is dependent on the number of cups of coffee, n, he drinks. From eight days of tracking he compiled the following data: People (P) 10 10 10 9 6 7 6 4 Cups of coffee (n) 1 2 2 3 4 4 5 5 Find the correlation coefficient r = Interpret the meaning of the slope of your formula in the context of the problem Use your model to predict the number of people that will complain about his attitude if he drinks 9 cups of coffee. How many cups of coffee should he drink so that no one will complain about his attitude? It is ok to round to one decimal place.

Question
A particular professor has noticed that the number of people, P, who complain about his attitude is dependent on the number of cups of coffee, n, he drinks. From eight days of tracking he compiled the following data:
| People (P) | 10 | 10 | 10 | 9 | 6 | 7 | 6 | 4 |
|---|---|---|---|---|---|---|---|---|
| Cups of coffee (n) | 1 | 2 | 2 | 3 | 4 | 4 | 5 | 5 |
Find the
r =
Interpret the meaning of the slope of your formula in the context of the problem
Use your model to predict the number of people that will complain about his attitude if he drinks 9 cups of coffee.
How many cups of coffee should he drink so that no one will complain about his attitude? It is ok to round to one decimal place.
