Chi Square Worksheet Show your work on separate paper 1. For each of the following situations, state whether you’d use a chi-square goodness-of-fit test, a chi-square test of homogeneity, a chi-square test of independence, or some other test. a) A brokerage firm wants to see whether the type of account a customer has (Silver, Gold, or Platinum)
chi-square-> 12.680 critical value-> 9.488 This time, the chi-square statistic (12.68) is above the =0.05 critical value, so you could reject the null hypothesis and declare that the cards are not random. The problem is clearly that there are too many jokers at the expense of clubs – you can see that from the z statistics. 3.

If H0 is true, the chi-square statistic X2 has approximately a ˜2 distribution with (r 1)(c 1) degrees of freedom. Where r = number of rows and c = number of columns. 4.The P-value for the chi-square test is P(˜2 X2). Given that all of the expected cell counts be 5 or more. 5.Decision: If P-value is less than level of significance, we reject H0.
