Panera Bread has found that 27% of customers purchase more than one cup of coffee per day from their shops. Suppose you randomly choose 185 of today's Panera Bread customers. Find the probability that no less than 33% of them purchased more than one cup of coffee from Panera. (Round to four decimals)
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.
Panera Bread has found that 27% of customers purchase more than one cup of coffee per day from their shops. Suppose you randomly choose 185 of today's Panera Bread customers.
Find the
We are given the Population proportion of customers who purchase more than 1 coffee per day, P = 0.27
Sample size , n = 187
Let "p" be the sample proportion of customers who purchase more than 1 coffee per day.
Since the sample proportion "p" is approximately normally distributed for large samples with mean P and standard deviation .
