Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

i) Determine P(X<2).
ii) What is the probability that none of the 25 boards are defective?
iii) Calculate the expected value and standard deviation of X.

A. When circuit boards used in the manufacture of compact disc players are
tested, the long run percentage of defectives is 5%. Let X = the number of
defective boards in a random sample of size n=25, stating the underlying
assumptions, answer the following questions:
