0.16. A random sample of 30 vehicles has a variance of 0.26. At a = 0.05, is there enough to reject the claim? Part 2: Correlation and Linear Regression: Label each part and box your answer are as follow 10. The maximum weights (in kilograms) for which one repetition of a half squat can be performed and the jump heights (in centimeters) for 12 international soccer players are as follow: Predictor Dependent variable variable Maximum weight Jump height (a) What is the r value? 190 60 185 57 (b) Is it a negative or positive correlation? 155 54 (c) Find the linear equation from this data 180 60 (d) What is the predicted height if a player is 175 56 186 in weight? 170 64 150 52 160 51 A)r = 0. 7556 160 49 180 57 B ) It is a positive correlation 190 59 because the coefficient of correlation 210 64 is greater than zero, ( positive value). C.) Equation of regression y = 20. 20956 + 0. 2093 x D) if x = 186kq then y = 59. 1 cm
