A small ferry runs every half hour from one side of a large river to the other. The number of cars X an a randomly chosen Ferry trip has the probability distribution shown below, You can cheek. that μx=3.87 and σx=1.29.
(a) The cost for the ferry trip is $5. Make a graph of the probability distribution for the random variable M≡ money collected on a randomly selected ferry trip. Describe its shape.
(b) Find and interpret μM
(c) Compute and interpret σ M.
