Question

number of bike rentals will be if the 'feels like' temperature is 41, the humindity is 57.7%, the windspeed is 27.8, the day is considered a holiday (1) and is a working day (1) and the weather is of type 3? Report your answer

Answer: (157.549513) + (-85.88732956) + ( 16.32800514 * 3)+ ( 7.643271095*41)+( -2.325852106*57.7)+( 0.590520174*27.8) = 316.2351081

2) All other things being equal, what change in the number of rentals do you estimate for an extra unit of windspeed? Enter the lower end of a 95% confidence interval on the worth of an extra windspeed and enter the upper end of the interval.

Answer: Windspeed 0.59052, Lower -2.289621606, Upper 3.470662

3) What proportion of variation in the number of bike rentals is explained by your regression model (by the independent variables)?

4)Test to see if the overall model is significant (i.e., if any of the independent variables are related to count) at the 0.01 level of significance.

Answer: H0: None of the independent variable is related to number rented, Ha: At least one of the independent variables is related to number rented

5) What is the P-Value

6) All other things being equal, how many more (less) rentals do you estimate will happen if the weather is of type 2 compared to weather of type 1?

7)State whether or not the difference in rentals between the two weather types is significant at the 0.01 level of significance; indicate the p-value you used to make your conclusion.

Answer: Not Significant (does not add explanatory power), P Value of type 2 weather vs type 1 = 0.435972496

Instructions:

Use a regression model that can be used to predict the total number of rentals ("count") as a function of the other factors in the data set.   When creating the regression model, assume that, "weekend" (0) is the base case for "working day," and weather type 1 is the base case for "weather."
