Binomial Distribution Problems

(1) A company owns 400 laptops. Each laptop has an 8% probability of not working. You randomly select 20 laptops for your salespeople.

(a) What is the likelihood that 5 will be broken?

(b) What is the likelihood that they will all work?

2) An HDTV is made from 100 components. Each component has a .005 probability of being defective. What is the probability that an HDTV will not work perfectly?

A Hypothesis Test for Dependent Samples

Example 1:

Two methods of memorizing difficult material are being tested. Nine pair of students matched according to IQ and background and then assigned to one of the two methods at random. A test is finally given to all students with the following results:

	1	2	3	4	5	6	7	8	9
Method A	90	86	72	65	44	52	46	38	43
Method B	85	87	70	62	44	53	42	35	46

Using the 0.05 level of significance is there a difference if effectiveness of the two methods?
