Question
the corrct answes are b, c, e. i hope u can give me explanation. thanks.
A manager is simulating the number of times a machine operator stops a machine to make adjustments, After careful study the manager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely Using the random numbers 0.1835 and 0.3094 (in that order), the next two simulated cycles would respectively have stops for adjustment of a. 2 and 2. *b. 1 and 2. c. 2 ad 1. d. 1 and 1. e. 2 and 3 12-40 (Ctrl) On cold mornings, the probability that David's car won't start is 0.22. When it doesn't start, he takes the bus and is late for work. When it does start, he drives to work on the freeway. Sixty-five percent of the time the freeway is clear, and he gets to work on time. The rest of the time he is late. Simulate 10 consecutive days worth of trips to work using the random numbers given (use the smaller numbers to represent "car won't start" and "freeway clear") Random numbers: Car 0.7772 0.2902 0.8120 0.2259 0.0527 0.2958 0.2891 0.0131 0.5219 0.9949 Traffic 0.2282 0.3674 0.1654 0.6909 0.7010 0.9802 0.5615 0.5604 0.4361 0.1405 12-42 How many times is David late for work because his car won't start? b. 1 c. 2 d. 3 How many times is David late for work? b. 1 d. 3 12-43Explanation / Answer

Using the above ranges, for RN=0.1835, No. of stops=1 and for RN=0.3094, No. of stops = 2. So, (b) is the correct answer.

Simulation results
No. of 'Late' given that car does not start = 2 times (day 5 and day 8). So, (c) is the correct answer.

Total No. of 'Late' = 4 (as per the 'outcome' column entry). So, (e) is the correct answer.
