In performing a chi-square test of independence, as the differences between respective observed and expected frequencies _________, the probability of concluding that the row variable is independent of the column variable increases. A. stay the same B. decrease C. increase D. double
A distribution and the observed frequencies of the values of a variable from a simple random sample of the population are provided below. Use the chi-square goodness-of-fit test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution Distribution: 0.1875, 0.1875, Observed frequencies: 16, 20, 24, 36 Significance level 0.05 0.3125, 0.3125 Determine the null and alternative hypotheses. Choose the correct answer below. OA. H: The distribution of the variable differs from...

(d) Test the observed frequencies ved frequencies against the expected frequencies using a goodness-of-fit ainst the expected freque test. The relevant critical value is x2 = 5.991. Show your work. e) Do these results support or contradict your prediction from question (a)? Explain in detail. 8. Most domestic cats (Felis cattus) are well-known junkies of catnip, Nepeta cataria. However, not all are. Some just ignore it. It turns out that other cat species, including leopards (Panthera pardis), respond to catnip...
Explain the difference between observed frequency and expected frequency as it relates to Chi-Square test.

The name given to goodness of fit test was derived based on the hypothesis tested and how good the observed frequencies fit a given pattern. To make a goodness of fitness test, the sample size should be large enough so that the expected frequency for each category is at least 5. There are four commonly used goodness of fit tests: The Chi-Square, Kolmogorov-Smirnov, Anderson-Darling, and Shipiro-Wilk. Observed frequencies, denoted by O, are counts made from experimental data - whereby you...
