10. The correlation coefficient for a set of 35 ordered pairs (x, y) is 0.968 where x = average number of grams of protein consumed daily and y = the maximium weight lifted during the performance of a bench press. Which of the following conclusions can be drawn from the r value?

Group of answer choices

There is a strong positive linear relationship between protein consumption and bench press maximums, which means higher protein consumption appears with heavier maximums.

There is a strong negative linear relationship between protein consumption and bench press maximums, which means higher protein consumption causes lighter maximums.

There is a weak positive linear relationship between protein consumption and bench press maximums, which means higher protein consumption appears with heavier maximums.

There is a weak positive linear relationship between protein consumption and bench press maximums, which means higher protein consumption causes heavier maximums.

There is a strong positive linear relationship between protein consumption and bench press maximums, which means higher protein consumption causes heavier maximums.

4) The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of...
