Guide to Worksheet 3-4
Worksheet No.3. The objective of worksheet No.3 is (i) to understand the idea of probability and frequency functions and (ii) to calculate the chance of the event of your interest.
- Use the concept of random variable effectively in order to find a specific probability
[1,2].
For example in Problem 2(d),
how do you express ``the demand exceeds the supply (8 copies)'' in terms of
?
- Can you recognize a ``binomial experiment'' in which you are counting the number of ``successes''? [3,4,5] For example in Problem 3, what is the ``success'' when you are counting the number of cars failing the inspection? What is the probability of success in this context?
Worksheet No.4. Here you are asked to show how you can apply the concept of normal distribution, critical point, and the central limit theorem in various problems.
- Identify the mean and the standard deviation parameter
of normal distribution,
and find the probability involving a normal random variable
.
[1-5]
- Learn how and when the critical point should be used. [2de,3b]
- Learn how to identify the distribution for the average
by using central limit theorem,
and use it to compute the probability involving the average
.
[4b,5b]
