a man Whitney test is used to evaluate the difference between two treatments, with a sample of n=10 participants in each treatment. using a two tailed test with a=.05, what value of U is necessary to conclude that there is a significant difference between

between treatments

Expert Solution

Here, n1=n2=10.

Significance level = 0.05

Two tailed test

Hence from the table of critical values for Mann-Whitney, we get the value U=23.

So if the test statistic exceeds this critical value U=23, we reject the null hypothesis and conclude tha there is a significance difference between the treatments.

Two samples each with n= 15 individuals are used to evaluate the difference between two treatment conditions. If the researcher uses a two-tailed test with α = .05, then the critical region for the t statistic begins at _________? a. t = + 2.145 b. t = + 2.131 c. t = + 2.048 d. t = + 2.045

In a test for the difference between two proportions, the sample sizes were n1 = 120 and n2 = 85, and the numbers of events were x1 = 55 and x2 = 45. A test is made of the hypotheses H0: p1 = p2versus H1: p1 ≠ p2. Compute the value of the test statistic. Can you reject H0 at the α = 0.05 level of significance? Can you reject H0 at the α = 0.01 level of significance?

Use an independent-measures t test with α = .05 to determine whether there is a significant mean difference between the two treatments.

The two-sample t-test is applied to compare whether the average difference between two groups is significant or if it is due instead to random chance. Use good references, 1. Briefly, describe the difference between Unpaired Two-Sample T-test and Paired Two-Sample T-test. 2. Provide an application example for Unpaired Two-Sample T-test, and stablish the Ho and Ha Hypotheses. 3. Provide an application example for Paired Two-Sample T-test, and stablish the Ho and Ha Hypotheses. 4. Explain the purpose of P-values and...

My classmate asked if they are understanding the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation. Does this explain how you would evaluate the variation and other methods to ensure that the data are appropriate to use for the test correctly. Within Group variations are variations are caused by the differences inside of the individual groups. No matter the amount of individuals groups there are, the values are not all the same. The qualities inside of the values will not...

Does this describe the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation? Why? or Why not?...

Does this describe the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation? Why? or Why not? The concept of a between-treatments estimate of Ơ2 and showed how to compute it when the sample sizes were equal. This estimate of Ơ2 is called the mean square due to treatments and is denoted MSTR. The numerator is called the sum of squares due to treatments and is denoted SSTR. The denominator, k – 1, represents the degrees of freedom associated with SSTR....
