Expert Solution
Answer 27
We can have a correlation coefficient value anywhere between -1 to +1, but not less than -1 and not more than +1
So, option A and B have acceptable values of correlation coefficient whereas option C has unacceptable value of correlation coefficient because the value of correlation given in option C is more than +1
So, option C is incorrect.
Answer 23
We have to find the relationship between the number of calories/serving and grams of fat/serving
we know, we can change the number of grams of fat per serving in order to change the number of calories per serving
Thus, explanatory or independent variable is grams of fat per serving and response variable or dependent variable will be calories per serving.
so, option C is correct answer
