s we know that square can nkt be negative so sum of square can not negative so a and b are incorrect options and r can be from -1 to 1. So option d is also incorrect. And as we know the equation of person correlation coefficient equation it will negative only if the sum of product wil be negative .
So (c) is correct option.

If the corelation between x and y is r = 0.82, which one of the following statements is true? The y-intercept of the least-square regression line is the point (0, 0.82). Low values of x are associated with high values of y. High values of x are associated with high values of y. The slope of the least-square regression line is m = b1 = 0.82.

ANSWER USING JAVA CODE (1)The sum of the squares of the first ten natural numbers is, 12 + 22 + ... + 102 = 385 The square of the sum of the first ten natural numbers is, (1 + 2 + ... + 10)2 = 552 = 3025 Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640. Find the difference between the...
