Scenario: 100 people were asked, “Who is your favorite superhero?” Below are the data. Test the null hypothesis that the population frequencies for each category are equal. α= .05.
Iron Man | Black Panther | Wonder Woman | Spiderman |
fo = 20 | fo = 30 | fo =30 | fo = 20 |
fe= | fe= | fe= | fe= |
The expected frequency, fe= ____
4
25
20
100
Chi Square test statistic = ______
6.55
4.00
8.00
3.50
degrees of freedom, df = ______, and the Chi Square critical boundary = ______
1; 3.84
3; 7.81
2; 5.99
4; 9.49
What is the correct result based on the data?
Retain H0; Not Significant; population frequencies equal
Reject H0; Significant; population frequencies NOT equal
Reject H0; Significant; population frequencies equal
Retain H0; Not Significant; population frequencies NOT equal
The correct APA format for the result would include

5. Interpretation of a chi-square test for goodness of fit Suppose you are reading a study conducted in the year 2000 about welfare recipients in the United States. The study consisted of a random sample of 199 welfare recipients, and provides summary statistics about various demographic characteristics of the sample, indluding household size broken down into five categories (one, two, three, four, and five or more persons in the household). You wonder if welfare recipients tend to live in different-...
Using the accompanying data below, perform a chi-square test using alphaαequals=0.01 to determine if the proportion of "Yes" observations differs between Populations A and B. Observed frequencies: Population Yes No A 18 20 B 22 20 Expected frequencies: Population Yes No A 19 19 B 21 21 Click the icon to view an excerpt from the table of chi-square critical values. What are the null and alternative hypotheses? A. Upper H 0H0: p Subscript Upper A Baseline not equals p...
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...
