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...
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 this assignment you will conduct hypothesis testing for Chi-Squared problems for both goodness of fit and independence-you will be given two Chi-Squared problems. For the Chi squared goodness of fit problem you need to: (1) state the populations and hypotheses; (2) solve for a Chi-squared goodness of fit test and show your work; (3) compute the answer using the SPSS program and paste the output information; (4) state the answer using proper APA format; (5) answer the question....
The test statistic for goodness of fit has a chi-square distribution with k - 1 degrees of freedom provided that the expected frequencies for all categories are a. 10 or more. b. k or more. c. 2k. d. 5 or more.
11. Testing Goodness-of-Fit with a Discrete Uniform: An observed frequency distribution is as follows: Number of successes Frequency 0 90 1 1 18 2 60 3 19 It is claimed that the above observed distribution comes from a Discrete Uniform Distribution. • What is the hypothesis of interest? • What are the expected counts? • What is the name and value of appropriate test statistic? • What is the pvalue ? What is your conclusion?
Suppose we are conducting a chi-squared goodness of fit test to test if a data set follows a uniform(0,16) distribution. We gather 30 observations and decide to use 5 equal probability intervals of the form: [a0, a1], [a1, a2],[a2, a3],[a3, a4],[a4, a5] We find our intervals, and find our test statistic to be 9.21. If we conduct our test using α = 0.05, would we a) Reject the null hypothesis b) Fail to reject the null hypothesis SHOW WORK
