Bassey Based on the following table, what would your decision be for this Chi-Square test with...
A chi-square for goodness of fit hypothesis test was conducted using an alpha of .05. The resulting chi-square was as follows: X2(2, n = 30) = 4.20, p > .05. Find the critical value. What decision was made regarding the null hypothesis?
If SPSS reports a "Sig." of 0.326 for a chi square and you are testing using an alpha level (α) of 0.01, the most appropriate decision would be to fail to reject the null hypothesis of your test. A. True B. False
I need help with this problem. Chi-Square Test A researcher is interested in determining whether an association exists between successful campaign fund raising and political success in elections. The following cross- tabulation displays the data she collected about the amount raised (characterized as either High/Low) and overall political success (coded as Successful/Not Successful). Calculate the chi-square and interpret your results. Assume an alpha = .05. Fund Raising Political Success Low High Totals Not Successful 24 6 30 Successful 8 22...
If the chi-square test is χ2(4, N = 71) = 3.472, then we ______. a. fail to reject the null hypothesis b. reject the null hypothesis c. reject the one-tailed null hypothesis d. reject the alternative hypothesis
You have conducted a Chi-Square test for Homogeneity. Below are your results. LaTeX: \chi^2=2.987 χ 2 = 2.987 LaTeX: \alpha\:=\:0.01\: α = 0.01 critical value = 5.991 What is your decision? Fail to reject Ho Reject Ho Not enough information
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.

What does it mean if the Chi-square test statistic has a value of zero? There is an error in the calculations as the test statistic must be positive. We will reject the null hypothesis. The test is right-tailed so that the result is inconclusive. All of the observed values equal the expected values for the corresponding cell.
Regarding the null hypothesis, what would be the decision made for a t-test of ‘no difference’ that returns a p-value of 0.000? Assume an alpha value of 0.05. A). Fail to reject the null hypothesis. B) Reject the null hypothesis.

You are conducting a multinomial Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies: HoHo : pA=0.4pA=0.4; pB=0.1pB=0.1; pC=0.2pC=0.2; pD=0.3pD=0.3 Complete the table. Report all answers accurate to three decimal places.
