34 - It is known that 25% of the customers who shop at the big shopping mall for more than 100 YTL, shop with a credit card. Since the standard error of the sample distribution of the rates for n=49 customers who shopped more than 100 TL is 0.062, find the probability that 28% to 30% of these n=49 customers use a credit card? A) 0.986 B) 0.1056 C) 0.347 D) 0.654 E) 0.342
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.
