A national survey asked people, "How often do you eat out for dinner, instead of at home?" The frequencies were as follows. Complete parts (a) through (g). Response Frequency Never 293 Rarely 392 Sometimes 899 Most of the time 386 Always 18 Click to select your answer(s).(a) Construct a relative frequency distribution of the data. Relative Response Frequency Never Rarely Sometimes Most of the time Always (Round to three decimal places as needed.)

Click here to win the standard normal distribution table (page 1). Click hore to view the standard normal distribution table (page 21. (a) What is the probability that a randomly selected car will get through the restaurant's drive-through in less than 124 seconds? The probability that a randomly selected car will get through the restaurant's drive-through in less than 124 seconds is (Round to four decimal places as nooded.) (bj What is the probability that a randomly selected car will spend more than 187 seconds in the restaurant's drive-through? The probability that a randomly selected car will spend more than 187 seconds in the restaurant's drive-through is (Round to four decimal places as needed.) (c) What proportion of cars spend betwoon 2 and 3 minutes in the restaurant's drive-through? The proportion of cars that spend between 2 and 3 minutes in the restaurant's drive-through is (Round to four decimal places as needed.) (d) Would it be unusual for a car to spend more than 3 minutes in the restaurant's drive-through? Why? The probability that a car spends more than 3 minutes in the restaurant's drive-through is . so be unusual, since the probability is than 0.05.
