Solution:
Please find the summary output for all the three variables below,
a)
Hence, The R-Squared values are the ones that are highlighted in Yellow.
b)
The best predictor for the number of units sold is Rainy days
because the R-Squared value is highest meaning the rainy day's
variables best explain the variation in the units sold. This is why
the best predictor of the number of units sold is rainy days
because of its high R-Squared value which determines the model
fit.
c)
The worst predictor is the price because it least explains the
variation in the number of units sold and hence is the worst
predictor of the number of units sold.
d)
With the given information we can determine the prediction model
that will help us in predicting future sales for the company. This
gives us an approximate value with which we can work. This
approximate value is known as the predicted value which is
predicted by the model that is based on past sales data. This is
why we will be in a better position to predict future sales and be
operationally ready to meet consumer demand.
Secondly, we can understand the factors on which the demand is dependent. Here, we came to know that the price is the worst indicator for the future sales predictor hence we can be in confidence that the increase in prices will not affect the demand much. Hence, such information has a big business advantage.
