1. (40 points) A Michigan travel agent wants to examine the relationship between the number of days temperatures exceed 40 degrees in December and the number of subsequent cruise bookings in January. Data from 10 years of bookings and temperatures were collected with the following results Days with Temps Over 40 in December Scatter Plot of Bookings and Days with Temps Over 40 degrees Bookings in January 150 178 100 64 233 169 250 13 17 10 16 150 100 6 25 10 21 Regression Statistics Multiple R R Square Adjusted R Square Standard Error Observations 0.91743195 0.841681382 0.821891555 26.85569546 10 Significance F Regression Residual Total 1 30674.57297 30674.57297 42.53101219 0000183879 8 5769.827031 721.2283788 36444.4 Coefficients Standard Error 242.0644525 18.53797901 13.05775847 1.1234SE-06 199.3157962 284.8131087 t Stat P-value Lower 95% U 95% Intercept X Variable 1 1.540026498 -6.521580498 0.000183879 -13.59471425 -6.492099302 A. Based on the scatter plot for the data, does it appear that a positive, negative, o relationship exists between number of days with temperatures above 40 in December and cruise bookings in January? r no linear number of a. Positive relationship b. Negative relationship C. No relationshipExplanation / Answer
Q.1) Given that, Variable X : the number of days with temperature above 40 in December.
Variable Y: the number of cruise booking in January.
Given scatter plot we can say that, as number of days with temperature above 40 in December increases the number of cruise booking in January decreases.
Therefore there is negative correlation between these two variables. That mean there is negative relationship between them..
Answer: b) Negative relationship
