Hey Tegra, this is the blog post that Dr. Guy put up last year and it was helpful in explaining this problem. I hope it helps. You are just using the Chi Square Analysis Calculator.
Assignment 5 - Problems 3, 4, & 5
--------------------------------------------------------------------------------
5. This problem requires the use of the Chi Square Calculator. Open the chi Square calculator and enter the number of rows (3) and the number of columns (3). Now enter the table into the calculator and click calculate.
You need to complete the hypothesis testing steps for this problem.
Here is the solution:
H(0): Crime rate and temperature are independent of each other.
H(1): Crime rate and temperature not independent of each other.
α = .05
Chi Square obtained = 29.26
Chi Square critical = 9.49 (use the table of chi square values to find this where df = (rows - 1) X (columns - 1))
Because the calculated value of chi square is GREATER than the critical value of chi square, reject H(0). In other words, crime and temperature are not independent of each other.
