Question
In: Statistics and Probability
Assume that Data Set A depicts the scores of 10 subjects who received either Treatment 1 or Treatment 2.
- Assume that Data Set A depicts the scores of 10 subjects who received either Treatment 1 or Treatment 2. Calculate a t-test for independent means to determine whether the means are significantly different from each other. In your complete answer, remember to include your t-statistic, critical value, and your decision about whether to reject the null hypothesis. For this question, you should assume that different participants received the two different treatments.

1. a. Assume that Data Set A depicts the scores
of 10 subjects who received either Treatment 1 or
Treatment 2. Calculate a t-test for independent means to
determine whether the means are significantly different from each
other. In your complete answer, remember to include your
t-statistic, critical value, and your decision about whether to
reject the null hypothesis. For this question, you should assume
that different participants received the two different
treatments.

1. Now assume that Data Set A depicts the scores of five
subjects who received both Treatment 1 and Treatment 2. Calculate a
t-test for dependent means to determine whether the means for the
two treatments were significantly different. The correlation
between the two treatments is +1.00. In your complete answer,
remember to include your t-statistic, critical value, and your
decision about whether to reject the null hypothesis. For this
question, you should assume that the same participants received
each...

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 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.

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. Complete an ANOVA table reporting the relevant SS, df, MS, and Fs. Also remember to include your critical value and whether you would reject your null hypothesis.

In certain drug trial, 10 subjects who received a placebo
reported headaches, while 30 subjects who received a placebo
reported no headaches. Of the subjects taking a new drug, 20
reported headaches, while 30 did not. a) Display this information
in a contingency table, including all totals. b) What percentage of
participants in the trial reported headaches? c) What percentage of
new-drug takers reported headaches? d) What percentage of placebo
takers reported headaches?
a) Draw a diagram to show a...
