Question
Example: Consider the following scatter charts and fill in the blanks. A. A student athlete's time (in minutes) to swim 2000 yards and the student's heart rate (beats per minute) after swimming on a random sample of 10 days. Correlation type: 160 140 a 120 100 80 60 40 20 TS = p-value = Linear Correlated? 33.5 34 34.5 3s 35.5 36 36.5 Swim Time Equation: Choose an appropriate value of x to predict a mean y: B. Average per capita wine consumption and heart disease rate in a random sample of 10 countriesExplanation / Answer
Solution A:
r = 0.126, r-square = 0.0159
TS = -0.3592, P-value = 0.7287
Linear correlated: NO
Equation: Y = 194.896 - 1.523X
