Part III. Chi-Square Goodness-of-Fit TestIn Lab 9 we investigated the primary personality categories of statistics students. The data are reprinted below.AnalystsDiplomatsSentinelsExplorers173Question #9 If statistics students are equally likely to be any of the four personality types, how many of eachpersonality type would we expect to see in our sample?Question #10 Write out the null and alternative hypothesis for this goodness-of-fit test.Question #11 Compute your test statistic by hand.Question #12 What is the sampling distribution of your test statistic (ie., what is the type of distribution andthe degrees of freedom)?7Question #13 Verify that the critical value for a 5% significance level is about 7.81, by looking at a ChiSquare table (Table F in the book, or find one online).

The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
Julius has conducted a very small study of the amount of sleep his dorm mates get each night. He believes that those who are on one of the school’s sports teams will get more sleep (measured in hours per night) than those who are not. Julius surveyed 12 people. Of these, 6 played on a sports team and 6 did not. The descriptive statistics from his survey are given below. PLAYS SPORTS (Sample 1) DOES NOT PLAY SPORTS (Sample 2) 8 6 9 6 8 5 7 7 8 7 7 6 What is the critical value for this test? what is the t-obtain value for this t-test? Based on your t-obtained value, what should you conclude about the null hypothesis for this test?
Give me an example of a research scenario where you would use an independent samples t-test. You can set up a situation where there is an experimental group and a control group, or maybe you want to compare two other groups of people (parents and non-parents, gender, partnered and single, etc). Give us a summary of what you would want to study, who your sample participants would be, why an independent samples t-test would be the best fit, and what statistically significant results would mean. Don't forget to include your research and null hypotheses!
One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing your score for this subsection, you're interested in the mean score, μ , among the general population on this subsection. The website reports that μ is 148 , but you believe that μ is greater than 148 . You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is 152 and that the standard deviation of their scores is 28 . Based on this information, answer the questions below. What are the null hypothesis ( H0 ) and the alternative hypothesis ( H1 ) that should be used for the test? H0 : μ is H1 : μ is In the context of this test, what is a Type I error?A Type I error is the hypothesis that μ is when, in fact, μ is .Suppose that you decide not to…
Page 160 #17 We predict that children exhibit more aggressive act after watching a violent television show. The scores for ten children were recorded before they watched a violent show and then after they watched a violent show. Aggression was measured in terms of number of aggressive acts (e.g. hitting, yelling, kicking etc). Sample 1 (after TV show): 5,6,4,4,7,3,2,1,4,1 Sample 2 (before TV show): 4,6,3,2,4,1,0,0,5,2 Is this a one-tailed or two-tailed test?
You may need to use the appropriate technology to answer this question. A certain manufacturer is a producer of aluminum components for the avionics and automotive industries. At its plant, an engineer has conducted a quality-control test in which aluminum coils produced in all three shifts were inspected. The study was designed to determine if the population proportion of good parts was the same for all three shifts. Sample data follow.

Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?
Compare and contrast (a.) single-sample t tests, (b.) paired sample t tests, and (c.) independent sample ttests in terms of participants recruited, data collected from each participant, and information we need toconduct the analysis.
Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation. Do we reject, or fail to reject, the null hypothesis?

Question #3 A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 298 vinyl gloves, 60% leaked viruses. Among 298 latex gloves, 13% leaked viruses. Using the accompanying display of the technology results, and using a 0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. View the technology results.
