1. 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 One 8.5, 7.9, 8.6, 8.4, 7.6, 9.1. Dosage Two- 8.1, 7.9 , 7.9, 7.6, 7.4. Control Group- 5.2, 5.6, 5.7, 5.9, 6.2, 6.4, 6.1.

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. (Continue as though all assumptions for ANOVA are met). How would you solve this without using excel?

1 A researcher was interested in comparing the response times of two different cab companies. Companies A and B were each called at n = 20 randomly selected times. The calls to company A were made independently of the calls to company B. The response times were recorded and the summary statistics were as follows: Company A Company B Mean response time 12.3 mins 15.0 mins Standard deviation 1.5 mins 1.7 mins Find the margin of error, E, for a...

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.

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,...
