To determine if the product is effective, a study is done with two groups of physiologically similar people. The placebo group is given a sugar pill, the treatment group is given the cold remedy, and the results are given below Cold duration (days) Placebo group (relative frequency) Treatment group (fnequency) 0-5 days 10-12 days 13+ days We want to determine...

A clinical trial was conducted to test whether a drug for treating insomnia is effective. Researchers administered the drug and measured the time it took 23 randomly selected subjects to fall asleep. The subjects had a mean wake time of 96.6 min and a sample standard deviation of 24.5 min. Assume that the population of wake times is normally distributed. (a) Construct a 95% confidence interval. You may use your calculator. Round to 1 decimals. (b) Are the assumptions met?...

You are interested in a new treatment for inflammation, as measured by C-reactive protein (hs-CRP). You enroll 7 people in your study, then flip a coin for each person. If they get a “heads”, you give them placebo for a month, measure their hs-CRP, wait a second month, and give them your new drug during the third month and measure hs-CRP again. If they get a “tails”, you give them your new drug for a month, measure their hs-CRP, wait...

The decision between a one- and two-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected. Many people believe that millennials are having more sex than people during the sexual revolution. You wonder whether the cohort currently in their mid-20s have had more sexual partners than older generations. Assume that the the average number of...

You have tested to find whether a relationship exists between hours of sleep the night before an exam and grade on the exam, You have a participant pool of n 30, df = 28. more hours of sleep receive higher grades on the exam. This is a directional hypothesis, so you run a one-tailed test, with o 0.05. You run the numbers and find a correlation of 0.243. The critical value from the t-table is Your hypothesis is that a...

Problem 1 The following data are from a research project on the effectiveness of a drug in reducing LDL cholesterol levels. While some patients in the study are assigned to the drug, others were given a placebo. Because the information about who is receiving the actual drug is kept confidential from those taking LDL measurements, that information is kept in a separate data set. Given below in Data Set A are the initial LDL cholesterol level of each individual before...

3. Binomial Test: A new medication that is designed to decrease anxiety was tested on 87 individuals that have been diagnosed with chronic depression. After the study. 36 of the test subjects reported a noticeable decrease in their anxiety and the other 51 subjects reported that they had noticed no change in their anxiety levels. Perform a binomial test on this dataset to determine whether or not the drug decreases anxiety in people with chronic depression. Reference Sections 18.1 and...
