Classic Golf Inc. manages five courses in the Jacksonville, Florida, area. The director of golf wishes to study the number of rounds of golf played per weekday at the five courses. He gathered the following sample information. Day Rounds Monday 124 Tuesday 74 Wednesday 104 Thursday 98 Friday 120 At the 0.05 significance level, is there a difference in the number of rounds played by day of the week? H0: Rounds played is the same for each day. H1: Rounds played is not the same. State the decision rule. Use 0.05 significance level. (Round your answer to 3 decimal places.) Compute the value of chi-square. (Round your answer to 3 decimal places.) What is your decision regarding H0?
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.

At the 0.05 significance level, is there a difference in the number of rounds played by day of the week?
H0: Rounds played is the same for each day.
H1: Rounds played is not the same.
State the decision rule. Use 0.05 significance level. (Round your answer to 3 decimal places.)
Compute the value of chi-square. (Round your answer to 3 decimal places.)
