Hello,
I have a 5 question timed quiz. Time limit is 40 minutes. The quiz is on the following topic: Correlation and regression

Login: I will give to whomever can take the quiz
Password: I will give to whomever can take quiz
Next you will click the class (only 1 there), then on the left hand side you will see homework tab, quiz tab and etc. Quiz 5 (highlighted in blue) is what I would like to be completed.
The quiz is timed at 40 minutes. And can be taken twice. (The teacher takes the better of the 2 grades).
The homework tab can be reviewed for an idea as to what we have been doing in class. (Click the homework tab on the left side, MML#6 is the current study and what the quiz will be on).
Thank you for your time.
(This week, we will look at describing relationships between two variables. Section 10.1 shows that the easiest way to display these relationships is to use a scatter plot. These graphs allow you to quickly see if there is any relationship. To verify this algebraically, we compute the correlation coefficient. This can tell us emphatically fi there is any relationship or not, depending on the value of r that is calculated.
Finally, if there is a relationship, we then learn to determine that relationship by computing the regression line (also known as the line of best fit or least squares line). When you are doing the calculations for these quantities, it is almost a necessity to use your calculator to enter the data and let it compute the values of a, b, and r for you.)
If the first quiz does not receive a 100% IT CAN BE TAKEN A SECOND TIME. But first review the quiz before it is closed out b/c the quiz will be very similar to the first just different numbers. I would need someone to log on to my account which I would provide my login and password for.
Thank you for your time.
