please use manual calculations do not use excel,
please
For each question, assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. 4. Assume that Data Set C depicts scores for 30 individuals who participated in a two-way independent groups design Analyze the data using a two-way ANOVA and complete an ANOVA table reporting the relevant DD, df, MS, and Fs Make sure to also report each of...
Assume that 18 subjects received one of three
treatments and produced the data reported in Data Set
B. Conduct a one-way ANOVA to see if the means of the
three treatments are different on a statistically significant
level, using a two-tailed alpha of .05. Complete an ANOVA table
reporting the relevant SS, df, MS, and F. Also remember to include
your critical value and whether you would reject your null
hypothesis. (20 points)
PLEASE NO EXCEL! THANK YOU :)

please explain throughly
It
doesn’t need sample data. That’s how the question was intended to
be.
Il. A friends someone has. A tailed test friends so was done to test whether the amount of narcissism is a good predictor of number of sample of 10 participants was used. Assume an alpha level of.05 and a two- of 9. What statistical test should you use to evaluate the hypothesis above? 10. What are the null and alternative hypotheses in words? Null...

Analyze the data using a two-way ANOVA and complete an ANOVA table reporting the relevant DD, df, MS, and Fs. Make sure to also report each of your critical values and indicate whether you would reject each of your three null hypotheses (i.e., main effect of A, main effect of B, interaction of A x B) Data Set C Variable B Variable...
I only need help with (e) and
(f). Thanks!

1. A study was conducted to explore the effects of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 got only water (control). Treatment 2 got lg of ethanol per kg of body weight, and treatment 3 got 2g/kg of ethanol. The amount of REM sleep in a 24hr period was recorded, in minutes. Data are below: Treatment 1: 63,...

Please answer all 9
questions
Question 1 (6 points) Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 59.2. The second instructor's grades have a variance of 72.5. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be...
The
z-tests
Help with this page is greatly appreciated. I dont understand
how to show a full diagram. Thanks in advance :)
The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...
