What are the two hypotheses of the F test?

In order for the F test to be significant, do you need a high or a low value of R2? Why? How are the standardized regression coefficients computed?

How are they useful?

What are their measurement units?

Calculate the test statistic F to test the claim that = . Two samples are randomly selected from populations that are normal. The sample statistics are given below. n1 = 25 n2 = 30 = 7.942 = 4.95

Test the following hypotheses by using the χ2 goodness of fit test.

You may need to use the appropriate technology to answer this question. Test the following hypotheses by using the χ2 goodness of fit test. H0: pA = 0.40, pB = 0.40, and pC = 0.20 Ha: The population proportions are not pA = 0.40, pB = 0.40, and pC = 0.20. A sample of size 200 yielded 60 in category A, 120 in category B, and 20 in category C. Use α = 0.01 and test to see whether the...

An ANOVA F test is an extension of a Question 1 options: two-sample z test. two-sample t test. two-sample test of proportions. a factorial ANOVA. Question 2 (2 points) Saved A manufacturer of infant formula is running an experiment using the standard (control) formulation and two new formulations, A and B. The goal is to boost the immune system in young children. There are 120 children in the study, and they are randomly assigned, 40 to each of the three...

What is the null and alternative hypotheses for a one tailed “greater than” test? In general, if some data we are working with is not normal, what one-sample test would you use (assume transformations do not work)? What are the assumptions for a one sample t-test? What are the assumptions for a two-sample t-test? In terms of coding, what is different between the two-sample t-test and the Welch approximation? Why would we use a paired t-test? Compare the two-sample t-test...
