Answer #1

Answer:

Given Data

C : The students belongs to a club

PT : The students works part time

Given That

P(C) = 0.4 ,

P(PT) = 0.5 ,

P(C & PT ) =  

= 0.05

We need P(C or PT)

=  

= P(C) + P(PT) -

= 0.4 + 0.5 - 0.05  

= 0.85

Let X denote the GPA of an engineering student at the CPP. It is widely known that, for this population, ?= 0.4. The population mean is not widely known, however, it is commonly believed that the average GPA is 2.9. We wish to test this hypothesis using a sample size of 16 and a level of significance of 0.05. What is the probability of a Type I error for this test? Answer to the two nearest decimal places.

Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering a question chosen at random from a universe of possible questions. (A strong student has a higher p than a weak student.) The correctness of answers to different questions are independent. Jodi is a good student for whom p = 0.83. (a) Use the Normal approximation to find the probability that Jodi scores 78% or lower on a 100-question test. (Round...
