A certain store sells only T-shirts. Let the random variable X represent the number of T-shirts bought from the store on any day
faltersainse [42]

Answer:

(a)\ \mu_y = 1125

(b)\ \sigma_y = 300

Step-by-step explanation:

Given

\mu_x = 75 -- Mean of T-shirts

\sigma_x = 20 -- Standard deviation of T-shirts

Rate = \$ 15

Solving (a): The mean of the revenue (\mu_y)

To solve this, we use:

\mu_y = Rate * \mu_x\\

This gives:

\mu_y = 15 * 75

\mu_y = 1125

Solving (b): The standard deviation of the revenue (\sigma_y)

To solve this, we use:

\sigma_y = \sqrt{Rate^2 * \sigma_2^2}

This gives:

\sigma_y = \sqrt{15^2 * 20^2}

\sigma_y = \sqrt{90000}

\sigma_y = 300
