Concept explainers
Refer back to Example 5.31. Two cars with six-cylinder engines and three with four-cylinder engines are to be driven over a 300-mile course. Let X1, … X5 denote the resulting fuel efficiencies (mpg). Consider the linear combination
which is a measure of the difference between four-cylinder and six-cylinder vehicles. Compute P(0 ≤ Y) and P(Y ≥ −2). [Hint: Y = a1X1 + … + a5X5, with a1 = 1/2 ,…, a5 = −1/3.]
