A hospital records the number of floral deliveries its patients receive each day. For a two-week period, the records show the following deliveries. 14, 28, 27, 23, 19, 20, 27, 20, 14, 27, 24, 25, 18, 22 Use exponential smoothing with a smoothing constant of 0.4 to forecast the number of deliveries.

You may need to use the appropriate appendix table to answer this question. Suppose that the average price for a gallon of gasoline in the Country A is $3.74 and in Country B it is $3.40. Assume these averages are the population means in the two countries and that the probability distributions are normally distributed with a standard deviation of $0.25 in the Country A and a standard deviation of $0.20 in Country B. (a) What is the probability that a randomly selected gas station in Country A charges less than $3.50 per gallon? (Round your answer to four decimal places.) (b) What percentage of the gas stations in Country B charge less than $3.50 per gallon? (Round your answer to two decimal places.) (c) What is the probability that a randomly selected gas station in Country B charged more than the mean price in the Country A? (Round your answer to four decimal places.)
