A researcher is trying to determine whether there is a difference in the number of new friends that students make during their freshman year based on whether they live on or off campus. The descriptive statistics for the two groups are presented below. Conduct the appropriate hypothesis test to determine whether there is a significant difference in the number of new friends made.

On-Campus Freshmen

Off-Campus Freshmen

X1 = 4.48 s1 =1.81 N1 =16

X2 =3.61 s2 =1.86 N2 =16

Summarize the data into the appropriate test statistics. Show your work.

d. Based on your results, evaluate the null hypothesis. Circle One: Reject H0

e. State your conclusions in terms of the original research question.

f. Compute Cohen’s d and interpret the effect (i.e., is it a small, medium, or large effect)

g. Compute the upper and lower limits of the 99% confidence interval for this test.

A researcher would like to determine if relaxation training will affect the number of headaches for chronic headache sufferers. For a week prior to training, each participant records the number of headaches suffered. Participants then receive relaxation training, and for the week following training the number of headaches is again measured. The number of headaches before and after training are provided in the table. a. Compute the appropriate mean and SS. (2 points each) b. Do the results indicate a...

To determine whether living in an off-campus residence affects an undergraduate student’s academic achievement at Longwood University, samples of 50 on-campus residents and 50 off-campus residents were drawn randomly and independently from the Longwood undergraduate student body. The GPA for the on-campus residents had mean 2.81 and variance 0.32, while the GPA for the off-campus students had a mean of 2.72 and variance 0.45. In this problem, you will conduct a two-sample z-test to determine if the data indicates that...

Suppose a researcher is trying to understand whether people who purchase fast-food hamburgers would be willing to pay more if the hamburger comes with a free cookie. Prior research suggests the mean amount customers say they are willing to pay for a hamburger is μ = 3.68 and σ = 0.70. The researcher plans to conduct a study very similar to the prior research by selecting a sample of customers and asking them how much they are willing to pay...

A researcher is interested in testing whether there is a difference in mean IQ level among people with varying levels of education (ED). For the ED variable, 1  =  no high school degree, 2  =  high school graduate, 3  =  college graduate. The researcher produces the following Minitab output. Use the Bonferonni method at the 3% significance level to test the hypothesis H0 :  μ1  =  μ3  vs  H1 :  μ1  ≠  μ3. --------------------------------------------------------- Descriptive Statistics: IQ ED N Mean...

A researcher wants to know whether a pharmaceutical intervention to reduce stress is working. N = 25 individuals are randomly assigned to receive the drug of interest and have a sample mean (M) of 76.4, whereas N = 29 individuals are randomly assigned to receive a placebo pill and have a sample mean of 83.0. Assume α = 0.05. The pooled variance (s2pooled) is calculated to be 12.72. The standard deviation of the distribution for differences between means (sdifference)is calculated...

  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, reaction time scores on the simulation task are normally distributed with μ = 210 and σ = 20.  The individuals in the sample had an average score of M = 222.             a....
