1) In an experiment a researcher wishes to determine if there is a difference in the level of relaxation subjects report while in either a hot or cold bath. He obtains the following scores: Sample 1: (hot) mean = 43, s2x =22.79, n = 15 Sample 2: (hot) mean = 39, s2x =24.6, n = 15 a. Compute the t obtained. b. With an α = .05, what is the tcrit ? c. What do you conclude about relaxation and hot and cold baths? d. compute the confidence interval if necessary e. compute the effect size if necessary

A researcher would like to determine whether an over-the-counter cold medication has an effect on mental alertness. A sample of n = 16 participants is obtained and each person is given a standard dose of the medication one hour before being tested in a driving simulation task. For the general population, scores on the simulation task are normally distributed with a μ = 60 a n d σ = 8 . The individuals in the sample had an average score...

A researcher wants to determine whether or not a given drug has any effect on the scores of human subjects performing a task of psychomotor coordination. The 9 subjects in Group A (Experimental Group) received an oral administration of the drug prior to being tested. Ten subjects in Group B (Control Group) received a placebo at the same time. The results of the experiment are shown below: Group A Group B 12 21 14 18 10 14 8 20 16...

A researcher would like to determine whether caffeine has an effect on mental alertness after sleep deprivation. A sample of n = 25 participants is obtained, and each person is given a cup of coffee, after one night of total sleep deprivation, one hour before being tested in a driving simulation task. For the general population with one night of losing sleep, scores on the simulation task are normally distributed with μ = 66. The individuals in the sample had...

1. Numerous studies have shown that IQ scores have been increasing, generation by generation, for years. The increase is called the Flynn Effect, and the data indicate that the increase appears to be about 7 points per decade. To demonstrate this phenomenon, a researcher obtains an IQ test that was written in 1980. At the time the test was prepared, it was standardized to produce a population mean of µ = 100 and σ = 15. The researcher administers the...

The goal of this experiment was to determine whether there is a difference between the happiness obtained from “material” versus “experiential” purchases (following the study of Van Boven & Gilovich, 2003). For our purposes, we’ll treat the “material” group as the control group, and ask whether the “experiential” group differed in their happiness rating. Again, the population mean was µ = 6.16 happiness, with standard deviation σ = 1.71. We collected a sample of n = 34 students in the...

A medical researcher wants to determine whether there is a difference in the mean length of time it takes three types of pain relievers to provide relief from headache pain. Several headache sufferers are randomly selected and given one of the three medications. Each headache sufferer records the time (in minutes) it takes the medication to begin working. The results are shown in the table. At a α = 0.01, can you conclude that the mean times are different? Assume...
