Answer:
a) 0.92; b) 84%
Step-by-step explanation:
First we enter the data into a graphing calculator. Use the values for X, The number of tourists, in the first list and the values for Y, the number of riders, in the second list.
Bring up the scatter plot and then run the linear regression. We get the equation
y = 1.59x + 5.06.
For part a,
The correlation coefficient, r, is 0.92. This means the equation is a good fit for the data.
For part b,
The coefficient of determination, r², tells us what percentage of variation in the dependent variable, y, is explained by the independent variable, x. This value is 0.84, which is 84%.
-3-3 = -6 ^ 2 = 36
-2- -4 = 2 ^ 2 = 4
36 + 4 = 40
square root of 40 = 2 -/10 ( 2 and square root 10)
