Two separate samples, each with n=15 individuals, receive different treatments. After treatment, the first sample has SS=1740 and the second has SS=1620. The pooled variances for the two samples is _________. Compute the estimated standard error for the sample mean difference. Estimated s(M1-M2)=________ If the sample mean
Can you please help me with these questions? Some I have attempted to answer. Please let me know if they are right or wrong. Find the estimated standard error for the sample mean for each of the following samples. (Use one decimal place) n=4 with SS = 48 _______ n=6 with SS= 270 _________ n= 12 with SS= 132 _____
A two tailed hypothesis test is being uses to evaluate a treatment effect with o= .05. if the sample data produce a z- score of z= -2.24 what is the correct decision? * reject the null hypothesis and conclude that the treatment has an effect * fail to reject the null hypothesis and conclude that the treatment has no effect
Can you please let me know if I answered these word questions correctly. My book isn't exactly to the point. i understand if you can't. Thank you You complete a hypothesis test using o=.05 and based on the evidence from the sample, your decision is to reject the null hypothesis. which of the following is true? * you have m

In a study examining the effects of alcohol on reaction time it was found that even moderate alcohol consumption significantly slowed the response time to an emergency situation in a driving simulation. In a similar study researchers measured reaction times 30 minutes after each participant consumed 6 ounces of wine. Again they

Whenever there are two independent variables and each independent variable has multiple groups, the most appropriate statistical test to use to compare these means and interactions is the two-way (factorial) ANOVA. Please see attachments:
Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some situations in which you might accept a higher level (e.g., 0.1)?
For the use of a one-way ANOVA there must be more than two means that are being compared. As a result, the following research question is proposed: Does a six week or 12 week self-monitoring program provided to teens between the ages of 13 and 15 diagnosed with ADHD reduce anxiety levels when compared with no intervention?

Running a test to specifically explain your results could be answered by using a two-tailed hypothesis test. What happens, assuming that you reject the null hypothesis? (Please see attachment).
Considerable focus will be directed toward hypothesis testing methods, analysis, interpretation, and related SPSS application. In hypothesis testing is to create a testable research hypothesis. This hypothesis will be formalized and written as a null hypothesis (Ho) and an alternative or research hypothesis (Ha). Please see atta
I am having trouble defining the 3 hypothesis' which is the very first step of this case. I realize that I would be using t-distribution for the first hypothesis, but I'm not sure where to go and I believe it is because I don't follow the way the assignment is worded.
