Suppose that the random variable X represents the length of a punched part in meters. Let Y be the length of the part in inches. Please report your answer in 2 decimal places.

- If E(X) = 5.6, what is the mean of Y?

1 m = 39.37 inches

Step 1

**Expected value:**

For a discrete random variable *X*, the expected value is the mean of the distribution. The expected value for *X* is denoted by E(*X*).

Step 2

**Mean of Y:**

It is given that *X *represents the length of a punched part in meters.

And, *Y* represents the length of the punched part in inches.

Mean of the *Y* can...
