No need to calculate, just answer:

1. say whether there is a strong positive linear correlation, weak positive linear correlation, strong negative linear correlation, weak negative linear correlation, or no linear correlation between the two variables.

2. describe how you can see this from the scatter plot and from the value you found for the correlation coefficient.

3. interpret this relationship in the context of the problem.

Such as:

1. Strong positive linear correlation.

2. From the graph we can see that relationship is upward means positive and data points are closed means a strong relationship.

3. It means that the higher the consumption of protein per day higher the diastolic pressure.

Question 1:

A study is conducted with a group of dieters to see if the number of grams of fat each consumes per day is related to cholesterol level. The data are shown here. If there is a significant relationship, predict the cholesterol level of a dieter who consumes 8.5 grams of fat per day.

Fat vs Cholesterol
Fat in Grams	Cholesterol Level
6.8	183
5.5	201
8.2	193
10	283
8.6	222
9.1	250
8.6	190
10.4	218
