A production manager knows that 5.5% of computer chips produced by a particular manufacturing process have some defect. A random sample of 5 computer chips are selected, whose characteristics can be assume to be independent of each other, were examined. Let X denotes the number of defective computer chips.
a) Explain how X is distributed?
b) Construct a probability distribution for the number of defective computer chips.
c) Represent graphically the probability distribution for (a) above.
d) Find the probability that;i. Exactly 2 computer chips are defectiveii. Between 4 to 5 computer chips are defective
e) What is the expected value of defective computer chips? Explain.
Explain your findings (including the logic of comparing within-group to between-group population variance estimates, how each of these is figured, and the F distribution).

Since they will be multiplying this average by the total number of customers to get an overall forecast, they would like to accurately estimate this average with a margin of error of less than $4000.
Chi-square tests are great to show if distributions differ or if two variables interact in producing outcomes. What are some examples of variables that you might want to check using the chi-square tests? What would these results tell you?
