Student federal loans: A Brookings Institution report, “Are College Students Borrowing Blindly?”, suggests that undergraduate students may be confused about their debt. For example, among all first-year U.S. undergraduate students with federal loans, 28 percent said they didn’t have any federal at all. Let’s assume this is true for the population of undergraduate students who have federal loans and set up a simulation to randomly sample 100 students from this population. For each sample, we calculate the proportion of students who report having no federal debt. We’ll repeat this process 500 times. The dotplot of the 500 calculated proportions is displayed below. Akers, B and Chingos, M. M. (2014). Are College Students Borrowing Blindly? http://www.brookings.edu/research/reports/2014/12/10-borrowing-blindly-akers-chingos In the dotplot, what does a dot represent? One first-year undergraduate student with federal debt. One random sample of 100 first-year undergraduate students with…

A researcher wishes to determine if violent television shows increase the tendency of young children to exhibit physical aggression. They have three video shows at their disposal – a cartoon with a high level of physical violence, an episode of Barney, a television show promoting understanding with little or no physical violence or aggression, and a ‘neutral’ show on how corn is grown. Design an experiment to address the researcher’s question using a repeated-measures ANOVA approach.

Use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?

Study 3: Two hundred people were randomly selected from a list of all people living in Minneapolis who receive Social Security. Each person was asked to participate in a statistical study, and all agreed to participate. Those who had no previous history of heart problems were instructed to take calcium supplements. Those with a previous history of heart problems were instructed not to take calcium supplements. The participants were followed for 5 years, and whether or not they had a heart attack during the 5-year period was noted. The researchers found that the proportion of heart attack victims in the calcium supplement group was significantly higher than the proportion of heart attack victims in the no supplement group. A) observational study or an experiment B) Did the study use random selection from some population? (Yes or No) C) Did the study use random assignment to the experimental groups? (Yes or No) D) Based on the description of the study, is it reasonable to conclude that…
CONFLICT RESOLUTION 3 of 4 What is the observed z/t-score? The Center for the Study of Violence wants to determine whether conflict-resolution program in a particular high school reduces aggressive behavior among its students. For 8 students, aggression was measured both before and after they participated in the conflict resolution course. What is the observed z/t-score? Their scores are below:
Measures of central tendency alone are insufficient to completely describe a sample because: a. in the amount of time required to calculate a measure of central tendency, the variable under consideration often changes. b. the value of central tendency for infinite populations is unknowable. c. two very different data sets can have roughly the same (possibly even identical) measure(s) of central tendency. d. there is rarely an unbiased measure of central tendency in reality.
A researcher is implementing an intervention where parents are taught advocacy skills. Fifteen parents are participating in the study and 15 parents are members of the control group. All 30 parents complete an empowerment scale, which is measured on a multi-item Likert scale. The researchers want to determine if there is a difference between the two groups of parents (intervention, control) on their empowerment score. What type of statistical test should be used? Group of answer choices Independent t-test Dependent t-test Chi Square ANOVA Correlation Analysis
Question Sample Results Evaluation. Kendall Jackson, CPA, is examining the operating effectiveness of the internal control of Town Mo, a large conglomerate in the music industry. As partof the evaluation, Jackson determined a necessary sample size of 93 items (based on a tolerable rate of deviation of 5 percent, an expected population deviation rate of 0.5 percent, anda risk of overreliance of 5 percent). After properly selecting the 93 items, Jackson found nodeviations from the prescribed control activities.a. If Jackson found three deviations in the sample, calculate the sample rate of deviationand use AICPA sample evaluation tables to determine the ULRD. What would Jacksonconclude with respect to the operating effectiveness of Town Mo’s internal control in thiscase?b. Using AICPA sample evaluation tables, determine the maximum number of deviationsthat Jackson could identify without reducing the reliance on Town Mo’s internal control.c. Repeat part (e) using a 10 percent risk of…
