18. The relationship between forced expiratory volume (FEV), which is measured in liters, and age, which is measured in years, is evaluated in a random sample of 200 men between the ages of 20 and 60. A simple linear regression analysis is performed to predict FEV from age. The Intercept (constant) = 8.0 and the Regression coefficient (slope) for Age = 0.29.

a. Interpret the regression coefficient for age in words. [PLEASE PROVIDE RATIONALE]

b. Interpret the intercept (constant) in words. [PLEASE PROVIDE RATIONALE]

In a study of whether a relationship exists between a child’s aptitude and the age at which he/she first speaks, researchers collected a random sample of 150 children and recorded the age (in months) of a child’s first speech (x variable) and the child’s score on an aptitude test (y-variable) The data were then used to create a regression equation in which the slope was calculated to be -1.25 and the y-intercept was calculated to be 109.

A study measured the relationship between the size of a truck’s engine (in liters) and its fuel economy (in mpg). It found a correlation coefficient of -0.9187, and a scatterplot of the data appeared to be approximately linear. Which of the statements below are true? Select all that apply. The correlation is strong, so even a small change in engine size is likely to impact fuel economy. In general, as engine size increases, fuel economy decreases. In general, as engine...
