2. There has been some research showing that amount of sunlight and amount of rain will affect the sugar
content of grapes and thus their quality to make wine. You measure the amount of sunlight, amount of
rain and sugar content of grapes across multiple vineyards and get the following correlations.
Amount of Rain
-.62
Amount of sunlight
.65
Sugar Content
Amount of sunlight
-48
1
a) How much variance in sugar content can be accounted for by amount of rain and sun?
b) What is the multiple correlation coefficient (i.e., R)?
c) If you know how much sun the grapes get, how important is it to know how much rain they also received
when predicting sugar content? Provide statistical evidence for your answer.
