- The degrees of freedom for a 2 x 2 cross-tabulation table for the chi-square test of independence equalIn the chi-square tests, the test statistics formula uses O and E notations. Explain the circumstancesunder which the chi-square test statistic values will be smaller or largerA veterinary study of horses looked at water sources for horses, and the investigators found that horses received water from a well, from city water, or from a stream. The investigators wanted to know if horses are equally likely to get water from each of those three sources. They collected data and observed the given values. Water Source Well City Water Stream Total Observed count 62 43 31 136 The cell that contributed least to the chi-square goodness-of-fit statistic is: - The city water cell with = 0.1201 - The well water cell with = 6.13 - The stream water cell with = 0.1201 - The city water cell with = 1/3
- A local restaurant claims that it gets 45 percent of its customers from Monday through Thursday, 20 percent on Friday, 20 percent on Saturday, and 15 percent on Sunday. How many degrees of freedom should be used to conduct a chi-square goodness-of-fit test of the claim? A) 3B) 4C) 6D) 7E) It is not possible to determine the degrees of freedom without knowing the sample size.Carry out a chi-square test for goodness of fit for the study (use the 0.01 level).if the results of a study using the chi-square tests are summarized as x2 ( 1,N=360) = 10.00,p<.01,then you would know that it was a what study?
