Suppose that 15% of the population of the chips are defective. If a random sample of 250 chips from the box is chosen, approximate the probability that fewer than 30 are defective. Use the normal approximation to the binomial with a correction for continuity. Round your answer to four decimal places.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
