Suppose you did a chi-square procedure with 50 subjects where there were four categories. What would be the degrees of freedom?
If there is K subjects and if each subjects has r categories then the df of chi square distribution is = (k-1)(r-1)
Here k = 50 , r = 4
So df = 49×3 = 147

What is the critical value for a chi-square test with 28 degrees of freedom at the 5 percent level of significance (3 pts)? If the chi-square test statistic were 41.10, what would you conclude regarding the null hypothesis (4 pts)? What would you conclude if the chi-square value were 48.19
-A chi-square test for goodness-of-fit has a sample size of 50. What are the degrees of freedom for this chi square? A. 25 B. The degrees of freedom cannot be determined from the information provided. C. 50 D. 49 -Rodney wants to test the relationship between college graduation rank and annual income. If income is measured on a ratio scale, the appropriate relationship test for Rodney to use is the: A. chi square test of independence B. independent-samples t test...
(1) Chi-square tests are nonparametric tests that examine nominal categories as opposed to numerical values. Consider a situation in which you may want to transform numerical scores into categories. Provide a specific example of a situation in which categories are more informative than the actual values. (2) Suppose we had conducted an ANOVA, with individuals grouped by political affiliation (Republican, Democrat, and Other), and we were interested in how satisfied they were with the current administration. Satisfaction was measured on...
Suppose that a response can fall into one of k = 5 categories with probabilities p1, p2, , p5 and that n = 300 responses produced these category counts. Category 1 2 3 4 5 Observed Count 48 63 73 49 67 (a) If you were to test this hypothesis using the chi-square statistic, how many degrees of freedom would the test have? degrees of freedom (b) Find the critical value of χ2 that defines the rejection region with α =...
Worksheet: Chi Square and Correlation Suppose we have three categories A, B, and C. Assume that the historical distribution of observations among these four categories is 20%, 40%, and 40% respectively. A sample of size 250 is taken, and we find 75 observations in category A, 125 in category B, and 50 in category C 1. a. State the null hypothesis for the Chi-square goodness-of-fit test. b. What are the expected frequencies for each category? c. Calculate the χ 2...

You intend to conduct a goodness-of-fit test for a multinomial distribution with 7 categories. You collect data from 74 subjects. What are the degrees of freedom for the x2 distribution for this test? d.f. = Submit License Question 1. Points possible: 1 Unlimited attempts. You are conducting a multinomial Chi-Square Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies: Ho:PA = 0.2; PB = 0.3; pc = 0.3; PD = 0.2...
Question 1 For Chi Square tests, all tests discussed can be used for both experiments and surveys True False Question 2 Chi Square tests have an assumption of normality True False Question 3 For a Chi Square test of Association, you ask if mouse hair color (black, grey or white) is associated with whisker length (short, medium or long). The df for this analysis would be: Give answer as X Question 4 The value of X^2 can be negative, zero,...
When Chi-square distribution is used as a test of independence, the number of degrees of freedom is related to both the number of rows and the number of columns in the contingency table. Select one: True False Question 2 Answer saved Points out of 1.000 Flag question Question text A goodness of fit test can be used to determine if membership in categories of one variable is different as a function of membership in the categories of a second variable...
5. The chi-square test for goodness of fit - No difference from a known population Aa Aa Suppose you are reading a study conducted in the year 2000 about welfare recipients in the United States. The authors report the following frequency data on the household size of the 2,352 welfare recipients in their random sample: Observed Frequencies Household Size 5-or-more-person 4-person 3-person 2-person 1-person 282 753 588 400 329 You wonder if welfare recipients tend to live in different-sized households...
