Question
Please show work/explain A particular class has 10 students. Suppose that the probability of getting an A in this c 2 out of 10) and the probability of getting a B is 3 see how likely this is to occur by chance. lass s 20% (or rather 0% (or rather 3 out of 10). We want to run a simulation to Part a: Using single digits from a section of the random di simulation. igit table, describe how you will run the Part b: Using line 113 from the random digit table (given below), carry out the simulation with 3 runs Line 113 61372 26590 75157 57974 20862 66909 88860 00930 rt e: Based on your simulation, how many of students got an A for each run? How many of the students in the simulation got a B?
Explanation / Answer
Part (a)
Simulation Process
Starting from the first digit, ‘6’ in line 113, pick 3 sets of 10 consecutive single-digits serially.
Each digit represents a student in the set. If the digit is 1 or 2, allot grade A to the student, if it is 3, 4 or 5, allot grade B to the student, and if the digit is 6, 7, 8, 9, or 0 allot grade C, say. to the student where C is other than A and B. ANSWER
