Suppose the random variable X has probability density function: \begin{equation*} f(x) = \frac{k}{x^2} \text{ for } 35 \le x \le 70 \end{equation*} Find the mean of X. Round your answer to 1 decimal place. Hints: • First you will need to find the value of k. The value of k will involve the fractions 1/35 and 1/70. • Then use the EXACT value of k when calculating the mean. • You should be using the equation: \begin{equation*} \mu = E(X) = \int_{-\infty}^{\infty} xf(x) dx \end{equation*}
