A researcher has two samples of participants, and each sample experiences a different level of the independent variable. Sample A has 8 participants and Sample B has 10 participants. The corrected variance for Sample A is 7.71 and the corrected variance for Sample B is 9.34.

What is the pooled degrees of freedom between the 2 samples? (hint: you shouldn’t use the pooled variance equation).

Find the pooled variance using the pooled variance equation.

c . Add the two variance versions of standard errors together and square root the result to find the standard error.

Using the total degrees of freedom, find the cutoff values for the two-tailed test at an alpha level of 0.05.

A researcher conducts an experiment consisting of two groups—Group 1, non-smokers, and Group 2, ex-smokers. Group 1 consists of 10 participants, while Group 2 has 12 participants. If the researcher conducts a two-tailed two-independent sample t-test, what will the degrees of freedom and the critical values at a 0.05 level of significance be? (Round your critical values to three decimal places.) degrees of freedom critical value (smaller value) critical value (larger value)

one sample has ss=36 and a second sample has ss=18 If n=4 for both samples, find each of the sample variances and compute the pooled variance. Because the samples are the same size, you should find that the pooled variance is exactly halfway between the two sample variances. The first sample has ________ (choose one of the following 12.00, 9.00, 6.00, 3.00), and the second has s^2=______((choose one of the folloeing 12.00, 6.00, 3.00, 4.50). The pooled variance is s^2p=________(9.00,...

Consider independent random samples from two populations that are normal or approximately normal, or the case in which both sample sizes are at least 30. Then, if σ1 and σ2 are unknown but we have reason to believe that σ1 = σ2, we can pool the standard deviations. Using sample sizes n1 and n2, the sample test statistic x1 − x2 has a Student's t distribution where t = x1 − x2 s 1 n1 + 1 n2 with degrees...

3. The t test for two independent samples- Two-tailed example AaAa? Bullying," according to noted expert Dan Olweus, "poisons the educational environment and affects the leaning of every child." Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a group...

* For large samples one sample t-tests (n >120) use critical t scores of ±1.96 (for 95% confidence level two tailed test) or ±1.65 (for 95% confidence level one tailed test). * For small samples (n<120) use critical t score obtained from t-distribution table. You will need to calculate degrees of freedom, which is simply the sample size minus 1 (df = n-1) and use an alpha value of .05. * For comparing means between two samples (regardless of sample...
