A researcher is interested in testing two different dosages of a new sleeping medication in a phase II clinical trial against a control group receiving a placebo. Suppose the following table observes the hours of sleep reported the preceding evening for subjects randomly assigned to each of the three groups. α = .05

Dosage I	Dosage II	Control
8.5	8.1	5.2
7.9	7.9	5.6
8.6	7.9	5.7
8.4	7.6	5.9
7.6	7.4	6.2
9.1		6.4
		6.1

*Continue as though all assumptions for ANOVA are met.

A) Calculate the MSB and MSW for a one-way analysis of variance procedure.

B) Using the information above, calculate an F statistic, and provide an interpretation of your p-value

Suppose a researcher is interested in the effectiveness of a new anti-hypertensive medication in a population of clinical trial participants with high blood pressure. In this particular study, the researchers decide to use each participant as their own control, offering the participants the study drug either preceding or proceeding a control period involving best standard of care. Assume the following sample of participants enrolled in the study represents an appropriate approximation to the normal distribution. Participant Systolic blood pressure (mmHG)...

A. A researcher was interested in comparing the GPAs of students at two different colleges. Independent simple random samples of 8 students from college A and 13 students from college B yielded the following results. The mean GPA for college A was x1 = 3.11, with a standard deviation s1 = 0.44. The GPA for college B was 2 = 3.44, with a standard deviation s2 = 0.55. Determine a 95% confidence interval for the difference, µ1-µ2 between the mean...

Q3. A or B? A pharmaceutical company is testing two new medication that alleviates rheumatism symptoms. 35 random patients tested drug A and 71% of them reported their symptoms are alleviated. 60 random patients (who are different from patients who tried drug A) tried drug B and 73% of them reported they felt better after taking the medication. Suppose, the pharmaceutical company would launch an advertising campaign if more then 70% of the patients report the medication is effective. What...

Scenario: Based upon the work of Elizabeth Loftus, a researcher was interested in testing the most effective way to implant false memories in people. First, she had all subjects watch a 60 minute movie. Then she randomly assigned these subjects to one of four conditions, each of which used different assessment techniques to influence subjects to think they saw something that didn't actually occur. Condition A utilized falsified photos, condition B utilized falsified video, condition C utilized misleading narrative,...
