One year consumers spent an average of $23 on a meal at a resturant. Assume that the amount spent on a resturant meal is normally distributed and that the standard deviation is $4. Complete parts (a) through (c) below. *** a. What is the probability that a randomly selected person spent more than $25? P(X> $25) = (Round to four decimal places as needed.) b. What is the probability that a randomly selected person spent between $13 and $20? P($13 < X <$20) = (Round to four decimal places as needed.) c. Between what two values, symmetrically distributed around the mean, will the middle 95% of the amounts of cash spent fall? The middle 95% of the amounts of cash spent will fall between X = $ and X=$ (Round to the nearest cent as needed.)
