I just wrote out all the possible choices and of the 36 choices, 27 of them had a product that was even. I don't remember the shortcut to this, but I just wrote out 1*1, 1*2, 1*3, etc.
Answer:
Hence, the data provides convincing evidence that a linear relationship exists between hours of sleep observed and academic performance as measured by GPA.
Step-by-step explanation:
Given the data:
Sleep (hrs) 9 8.5 9 7 7.56 7 5.5 6 8.5 6.5 8
GPA 3.8 3.3 3.5 3.6 3.4 3.3 3.2 3.2 3.2 3.4 3.6 3.1 3.4 3.7
The scatter plot shows a positive linear trend. With the correlation Coefficient depicting a R value of 0.56. The residual plot also depicts a a randomly scattered values of the residual values. Similarly, a plot of the normal values of residuals
*Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + 5^2 - c^2
36 + 25 = c^2
61 = c^2 *Square root 61
c^2 (c squared) = about 7.8
