Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The correlation between the heights of fathers and the heights of their (fully grown) sons is r = 0.52. This value was based on both variables being measured in inches. If fathers’ heights were measured in feet (one foot equals 12 inches), and sons’ heights were measured in furlongs (one furlong equals 7920 inches), the correlation between heights of fathers and heights of sons would be
A
much smaller than 0.52
B
slightly smaller than 0.52
C
unchanged:equal to 0.52
D
slightly larger than 0.52
E
much larger than 0.52
Explanation: 

Detailed explanation-1: -Correlation quantifies the direction and strength of the relationship between two numeric variables, X and Y, and always lies between-1.0 and 1.0. Simple linear regression relates X to Y through an equation of the form Y = a + bX.

Detailed explanation-2: -The model dictates that 25 percent of variations in the height of son can explained by the height of father.
