In the following picture there is a box diagram or two variables containing the annual income of mayors and annual income per person for a sample of 32 towns in Puerto Rico The distribution of annual income of the mayors in this 32 towns of Puerto Rico are: A. Can’t tell B. Symmetric C. Skewed to the left D. Skewed to the right
A mayor running for re-election claims that during his term, average municipal taxes have fallen by $125. A conscientious statistician wants to test this claim. He surveys 37 of his neighbors and finds that their taxes decreased (in dollars) as follows: 121, 139, 121, 125, 118, 145, 141, 91, 127, 136, 144, 154, 131, 139, 139, 125, 108, 130, 125, 106, 137, 148, 154, 134, 137, 112, 96, 114, 114, 126, 133, 129, 94, 129, 148, 163, 121 The statistician assumes a population standard deviation of $19. Do you think the statistician should reject the mayor's claim? Why or why not? Step 1: State the hypothesis. ?v= Step 2: Determine the Features of the Distribution of Point Estimates Using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are [Select an answer with distribution mean and distribution standard deviation Step 3: Assuming the Claim is True, Find the Probability of Obtaining the Point Estimate.

Selecting the Appropriate Inferential Test: For each of the studies below, please identify the following (or indicate N/A "not applicable" if the feature is not relevant to the design): a) Independent Variable(s) (IVs) and # of levels for any IVs (for Correlation/Regression, identify the predictor and predicted variable rather than IV and DV) b) Dependent Variable (DV) c) Scale of Measurement for the Dependent Variable: (Nominal, Ordinal, Interval, Ratio) for Correlation/Regression please make sure you identify the scale of measurement for both variables d) Appropriate Statistical Test (If it is a Factorial ANOVA, make sure to name the design: e.g., 2 X 2, 2 X 3, etc.)
10. For adults, certain type of cancers can be treated with multiple health interventions. To gain information about all Maryland-based treatment centers a survey is sent to a randomly chosen group of 25 Maryland based treatment centers that asks about the recommended interventions for cancer patients based on medical records, insurance, and income. All of the randomly selected treatment centers completed the survey. The sample is: For adults, certain type of cancers can be treated with multiple health interventions.

17. The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.4% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full-time freshmen from the survey. You are interested in the number that believes that same-sex couples should have the right to legal marital status.What is the probability that at least two of the freshmen reply "yes"? (Round your answer to four decimal places.)

Seven percent of those who invest in mutual funds consider corporate stocks to be “very safe”, 58% consider them “relatively safe”, 24% consider them “not very safe”, 4% consider them “not safe” and 7% "They are not safe at all." Business / Week / Harris asked 550 mutual fund investors how they would rate corporate bonds for safety. The answers were the following Seguridad Frecuencia Very safe 62 Relatively safe 323 Not very safe 76 Not safe 26 Not safe at all 63 Does the attitude of mutual fund investors differ from corporate bonds from their attitude to corporate stocks? Support your conclusion by giving a statistical test. Use α = 0.01. For this problem you must present: -Hypothesis-Result of the expected values, residuals and the calculation of the test statistic.-Analysis of the results in the chi square test and its conclusion in applied terms of the problem
2. A political scientist developed a test designed to measure the degree of awareness of current events. She wants to estimate the average score that would be achieved on this test by all students in a certain high school. The administration at the school will not allow the experimenter to randomly select students out of classes in session, but it will allow her to interrupt a small number of classes for the purpose of giving the test to every member of the class. Thus, the experimenter selects 25 classes at random from the 108 classes in session at a particular hour. The test is given to each member of the sampled classes, with results as shown in the accompanying table. Number of students, mi Total score, yi Class 1 31 1590 2 29 1510 3 25 1490 4 35 1610 5 15 800 6 31 1720

Imagine you are a researcher interested in the effects of marijuana on beliefs in conspiracy theories. The study involves two groups, to which people are assigned by chance: Group A takes a pill that contains the active ingredient in cannabis, THC, while Group B are given a harmless placebo pill. Neither the people conducting the study nor the participants know who is getting the drug and who is not. After taking the pill and completing some filler tasks, participants are given a series of surveys to complete. One of these theories asks them to indicate the extent to which they believe in different conspiracy surveys (e.g., a secret group like the Illuminati controls the world, Obama was not born in the US & is secretly a Muslim, 9/11 was an inside job, the moon landing was faked).
