random experiment was conducted where a Person A tossed five coins and recorded the number of “heads”. Person B rolled two dice and recorded the average the two numbers. Simulate this scenario (use 10000 long columns) and answer questions 10 to 13.

Hint: check Lectures 26 and 27 in the Book.

a. Person A

b. Person B

c. Not possible to determine

11. Which of the two persons will have higher Median among their outcomes?

a. Person A

b. Person B

c. Not possible to determine

12. What is the probability that person B obtains number 5 or 6?

a. About 10%

b. About 20%

c. About 30%

c. About 55%

13. Which of the persons has higher probability of getting the number 3 or larger?

Suppose a coin is tossed 100 times and the number of heads are recorded. We want to test whether the coin is fair. Again, a coin is called fair if there is a fifty-fifty chance that the outcome is a head or a tail. We reject the null hypothesis if the number of heads is larger than 55 or smaller than 45. Write your H_0 and H_A in terms of the probability of heads, say p. Find the Type I...
