Answer:
Correct statement: (a) and (b).
Step-by-step explanation:
R-squared is a statistical quantity that measures, just how near the values are to the fitted regression line. It is also known as the coefficient of determination.
The coefficient of determination is the squared value of the correlation coefficient.
That is,
![R^{2}=(r(X, Y))^{2}](https://tex.z-dn.net/?f=R%5E%7B2%7D%3D%28r%28X%2C%20Y%29%29%5E%7B2%7D)
The correlation coefficient between two variables is the measure of the strength and direction of the relationship between two variables.
Its values ranges from -1.00 to +1.00.
Although <em>r</em> can be negative but R² is always positive, since square of a negative number is also positive.
So the correct statements are:
a. cannot be negative
b. is the square root of the coefficient of correlation
Answer:
The answer is 2!!!
Step-by-step explanation:
If you would like to find the elapsed time between 10:30 p.m. and 1:15 a.m., you can calculate this using the following steps:
12:00 p.m. - 10:30 p.m. = 1:30
00:00 a.m. + 1:15 a.m. = 1:15
1:30 + 1:15 = 2:45 = 2 hours and 45 minutes
The correct result would be <span>2 hours and 45 minutes.</span>
