Vivian Lowe is planning a surprise party for her husband’s 50th birthday. She has decided to serve shish kabob. The recipe that she is using calls for two pineapple chunksfor each shrimp. She plans to size the kabobs so that each has three shrimp. She estimates that a single pineapple will yield about 50 chunks, but from past experience,about 1 out of every 10 pineapples is bad and has to be thrown out. She has invited 200people and expects that about half will show up. Each person generally eats about 2kabobs.b. Suppose that the number of guests is a random variable having the normaldistribution with mean 100 and variance 1,680. If she wants to make enough kabobsto feed all the guests with probability 95 percent, how many pineapples should shebuy?
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.
