A medical researcher is comparing the effectiveness of two treatments. Sample data is as follows:

Sample A: Time to recover = 8 days   s = 2.5 days    n = 20

Sample B: Time to recover = 11 days   s = 3.5 days    n = 16

Perform a hypothesis test at 95% confidence to determine whether there is a significant difference in the time to recover between the two treatments. Be sure to state your null and alternate hypothesis, show your test statistic, show p-value, and state your conclusion: are the treatments significantly different?   YES or NO. Assume that the data is normally distributed.

Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two independent test groups. The first group consisted of 7 people with the illness, and the second group consisted of 12 people with the illness. The first group received treatment 1 and had a mean time until remission of 199 days, with a standard deviation of 6 days. The second group received treatment 2 and had a mean time...

A researcher is evaluating the effectiveness of an anti-truancy program for youth. A sample of at-risk youth were selected to participate in the program, and their number of days truant per month were recorded before they completed the program and then again afterward. The data are below. Use a five-step hypothesis test and an alpha of .05 to test the hypothesis that the program significantly reduced youths' truancy. Type or neatly write all five steps clearly, with steps labeled and...

Doctors are comparing the efficacy of two painkillers. They randomly assign one of the two painkillers to their patients and measure time to relief for each individual. The group assigned painkiller 1 has 41 people in it. The group assigned painkiller 2 has 61 people in it. For group 1, the mean time to relief is 10 minutes, and the sample variance is 2 minutes. For group 2, the mean to time to relief is 9.5 minutes, and the sample...

ANOVA hypotheses—A researcher interested in investigating the effectiveness of two drugs randomly divides 150 volunteers into five equal groups—placebo, double dose of drug 1, single dose of drug 1, double dose of drug 2, single dose of drug 2—then measures the platelet level of each patient. Write the appropriate hypotheses to test the hypotheses that at least one of the population mean platelet levels for these treatments are different. Be sure to identify your parameter and label your groups appropriately.

Research Scenario #1 A researcher hypothesizes that zylex, a new antidepressant, will affect concentration. It is known that scores on a standardized concentration test is normally distributed with a µ= 50 and a σ= 12. A random sample of n=16 participants, aged 19-35, are chosen from the State of New Jersey. The sample is put on a six month dosage plan of zylex. After six months, all the participants are given a standardized concentration test. The researcher records the data...
