A chi-square test for goodness of fit is used to examine the distribution of individuals across three categories, and a chi-square test for independence is used to examine the distribution of individuals in a 2×3 matrix of categories. Which test has the larger value for df? a. The test for independence b. Both tests have the same df . c. The df value depends on the sizes of the samples that are used. d. The test for goodness of fit

In performing a chi-square goodness-of-fit test for a normal distribution, a researcher wants to make sure that all of the expected cell frequencies are at least five. The sample is divided into 7 intervals. The second through the sixth intervals all have expected cell frequencies of at least five. The first and the last intervals have expected cell frequencies of 1.5 each. After adjusting the number of intervals, the degrees of freedom for the chi-square statistic is ____. 2, 3,5,...

QUESTION 5 In a goodness-of-fit test to see if a set of 100 values were randomly drawn from a normal distribution, the quartiles and median (i.e., the 0.25, 0.5, and 0.75 quantiles) for the normal distribution were used to determine intervals for sorting the data. What is the expected number of values that fall into each interval assuming the 100 numbers were drawn from the normal distribution? QUESTION 6 Consider again the goodness-of-fit described in the previous problem. Assuming that...
