Determine (a) the chi squared χ2 test statistic, (b) the degrees of freedom, (c) the critical value using α=0.05, and (d) test the hypothesis at the α=0.05 level of significance. H0: pA = pB = pC = pD = 1/4th H1: At least one of the proportions is different from the others. (a) The test statistic is __?__ . (Type an exact answer.)
Why is the F statistic also called an F ratio? Select one: a. It is the ratio of the sum of squares to the means b. It is the ratio of degrees of freedom c. It is the ratio of one group mean to another. d. It is the ratio of the mean square between to the mean square within.
The One-way ANOVA F test statistic can be calculated using which formula? a. F = MSBetween / MSTotal b. F = SSBetween / SSTotal c. F = MSBetween / MSWithin d. F = MSWithin / MSBetween
Hi, I'm considering the following question: "Let's say we just calculated the t-test statistic for the following hypotheses: H0: mu <= 34, Ha: mu > 34. The sample size was 25, and the test statistic turned out to be -2.84. What would be the correct conclusion? A- Do not reject the H0 - the p-value is smaller than alpha B- Reject the H0 - the test statistic is more extreme than the critical value C- Reject the H0 - the...

I spefically need to see how the test statistic and critical value is calculated. Test the claim that the proportion of men who own cats is significantly different than 80% at the 0.02 significance level. The null and alternative hypothesis would be: The test is: left-tailed right-tailed two-tailed Based on a sample of 55 people, 78% owned cats The test statistic is: (to 2 decimals) The positive critical value is: (to 2 decimals) Based on this we: Reject the null...

b) At a 5% level of significance, what is the critical value of the test statistic? Round to four decimal places. A. 5.9914 B. 3.8415 C. 9.4877 D. 13.2767 c) What are the degrees of freedom of the test statistic? A. 1 B. 299 C. 2 D. 4 Many companies use well-known celebrities as spokespersons in their TV advertisements. A study was conducted to determine whether brand awareness of female TV viewers and the gender of the spokesperson are independent....
The test statistic used in the F test for the equality of two variances is calculated as F = s12/s22. In this formula, s12and s22 represent the sample variance for sample 1 and sample 2, respectively. True or False?
