- A study is conducted to investigate the association between income level and political party affiliation in the USA. Income level has 5 levels: Lowest (lowest 20-th percentile), low, middle, high, and very high (top 20-th percentile). Political party has 3 categories: Democratic (D), Independent (I), and Republican (R). A baseline category logit multinomial is fit on the 3 response categories using covariate of income level as ordinal (with scores 1, 2, 3, 4, and 5 for the categories lowest, low, middle, high and very high respectively). Base category of response is Independent. The fitted model is log(ˆπD/πˆI ) = 3.3 − 0.2x and log(ˆπR/πˆI ) = 1.0 + 0.3x, where x=1,2,3,4,5 (poverty levels as numeric/ordinal), πD is the probability of being Democrat, πI is the probability of being Independent, and πR is the probability of being Republican. a. Comparing the chances/probability of being Republican to Independent, interpret the effect of income level increases on the odds (of being…Define what an endogenous variable is, describe three scenarios that may cause a problem of endogeneity, and what are minimal assumptions needed for a good instrument. Tobit models are used to model censored and corner solution data. Explain what the difference between these two types of data is, and how does it affect the interpretation of Tobit models? What is the difference between a logit and a probit model, and why would are they preferred over a linear probability model (LPM) Explain what it means for a variable to possess a unit root. What are the implications for regression analysis if one uses variables with Unit roots? Explain what serial correlation is, how do you test for it, and why it invalidates the standard calculation of standard errors in time series data. Describe what does it mean to have a spurious regression, why could it happen, and what are the consequences in terms of t-statistics and goodness of fit measures?Researchers at Purdue University and Wichita State University found that airlines are doing a better job of getting passengers to their destinations on time. AirTran Airways and Southwest Airlines were among the leaders in on-time arrivals, with both having 88% of their flights arriving on time. But for the 12% of flights that were delayed, the dataset named AirDelay contains this information. - View the infotmation (data that realtes to the question) in the screenshot attatched. A) Formulate the hypothesis that can be used to test for a difference between the population mean minutes late for delayed flights by these two airlines. B) Identify the appropriate t-test. Explain your selection. C)Conduct the test using an α = .05. D) Interpret your results in the context of this problem.
- After the pandemic hit and people were forced to spend more time indoors, there have been a suspicion among health professionals. that people are eating more and thus gaining weight.

CNet.com offers online reviews of all major cell phones, including battery life tests. In a review of the iPhone6, the talk-time battery life of 35 iPhones was measured. Similarly, the talk-time battery life of 30 Galaxy S6s was measured. Two outputs are given below. Which is appropriate for analyzing the data collected? Output 1 Output 2 Using the StatCrunch output chosen above, determine if there is a difference in the mean battery life for the two phones. Use a significance level of 0.01 when conducting the test.

- Using google collabs to find the data (phyton)At what age do babies learn to crawl? Does it take longer to learn in the winter when babies are often bundled in clothes that restrict their movement? Data were collected from parents who brought their babies into the University of Denver Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported the birth month and the age at which their child was first able to creep or crawl a distance of four feet within one minute. The resulting data were grouped by month of birth. The data are for January, May, and September AverageBirth month crawling age SD nJanuary 29.84 7.08 32May 28.58 8.07 27September 33.83 6.93 38 Crawling age is given in weeks.

One measure of HRV is the average of normal-to-normal beat interval (in milliseconds) for a 24-hour time period. Twenty-two heart attack patients who were dog owners and 80 heart attack patients who did not own a dog participated in a study of the effect of pet ownership on HRV, resulting in the summary statistics shown in the accompanying table.

- The goal of a ________ is to explain the relationship between observed phenomena, without necessarily being directly testable. datum theory hypothesis quantitative studyIron is an essential nutrient. Iron deficiency has beenlinked with symptoms such as anemia, rapid heartbeat,increased risk of infections, and lightheadedness. At theother end of the spectrum is iron overload, describedin an August 2012 New York Times article. Excess ironis deposited in the liver, heart, and pancreas and cancause cirrhosis, liver cancer, cardiac arrhythmias, anddiabetes. According to a Framingham Heart Studyresearcher, “About one person in 250 inherits a geneticdisorder called hemochromatosis that increases ironabsorption and results in a gradual, organ-damagingbuildup of stored iron.” Suppose we have a random sample of 1000 adults, and want to find the probabil-ity that at least 5 of them have this disorder. Which of these statements is true? I. We would expect 4 of these people to have hemo-chromatosis. II. We can calculate this probability using a Binomialmodel.III. We can approximate this probability using a Normalmodel.A) None B) I only C) I and II onlyD) I and III…People with chronic airflow obstruction are believed to have a limited exercise tolerance. This limited tolerance is thought to be mainly due to impaired ventilation mechanics. In a study designed to measure the effect (if any) that a new treatment had on the exercise capacities of individuals with chronic airflow obstruction, investigators measured, among other things, maximum exercise ventilation (VEmax) before and after the treatment was applied. The raw VEmax data are reproduced in the table below. The investigators would like to determine if there was an increase in the maximum exercise volume as a result of the treatment. Let ? = 0.025.
