Answer #1

Solution :-

A slope of 0 implies no statistically significant correlation.

Ans = 0

-----------------------------------

A value of zero indicates that there is no relationship between the two variables. If the correlation coefficient of two variables is zero, it signifies that there is no linear relationship between the variables.

Anytime the correlation coefficient, denoted as r, is greater than zero, it's a positive relationship. Conversely, anytime the value is less than zero, it's a negative relationship. A value of zero indicates that there is no relationship between the two variables.
