The following regression uses data on illegal downloading of music. A sample of 500 individuals were asked whether they had downloaded music illegally (theft). In addition, respondents also gave answers to the following; caught: a respondent's belief of her chances of getting caught if she attempted to act illegally (0-10, 10 being “great risk") penalty: a respondent's belief regarding how severe her penalty would be if she got caught (0-10, 10 being “great risk) gender: gender, where male is 1 and female is 0 Edu: years of formal education Income: Income of the respondent (£)

We expect a car's highway gas mileage to be related to its city gas mileage (in miles per gallon, mpg). Data for all 1259 vehicles in the government's 2019 Fuel Economy Guide give the regression line highway mpg = 8.720+ (0.914x city mpg) for predicting highway mileage from city mileage. O Macmillan Learning (c) Find the predicted highway mileage, y, for a car that gets 14 mpg in the city. Give your answer to three decimal places. y = mpg Find the predicted highway mileage, y, for a car that gets 21 mpg in the city. Give your answer to three decimal places. y = mpg
In a certain jurisdiction, all students in Grade Three are required to take a standardized test to evaluate their math comprehension skills.The file contains these data resulting from a random sample of n=30 schools within this jurisdiction. From these data you wish to estimate the model Yi=β0+β1Xi+ei where Xi is the percentage of Grade Three students in School i who live below the poverty line and Yi is the average mathematics comprehension score for all Grade Three students in the same school, School i. The observed data for the X variable is labled perbelowpoverty and the observed data for the Y variable is labeled mathscore in the file.Import (either hand type or load the file) data into R Studio, then answer the following questions based on the data.(a) Create a scatterplot of the data. What can you say about the nature of the relationship between the percentage of Grade Three students living below the poverty line in a certain school and the school's average Grade Three…
Suppose when you add flexibility to your model by adding higher-order terms or more predictor variables that you begin to see the test or validation error (MSE or SSE evaluated on the test or validation set) begin to increase away from the training error. What kind of a problem are your models experiencing?
Chronic wasting disease is a fatal disease of deer and elk believed to be caused by transmissible prions. The origin, development, and spread of chronic wasting disease in free-ranging deer and elk populations are not well understood. One factor directly related to the control of chronic wasting disease is the incubation period in free-ranging animals. Boxplots are shown for estimates of the incubation period of chronic wasting disease in North American deer and elk between 2011 and 2016. Incubation period of chronic wasting disease in North American deer and elk 80- 70- 60- 50- 40- 30- 20- 10- 2011 2012 2013 2014 2015 2016 Year
The y-interept bo of a least-squares regression line has a useful interpretation only if the x-values are either all positive or all negative. Determine if the statement is true or false. Why? If the statement is false, rewrite as a true statement.
11. In this same article on sleep duration and start time, researchers also considered whether school start time was related to obtaining an adequate amount of sleep. An adequate amountbof sleep was considered at least 8.5 hours of sleep, as recommended by the National Sleep Foundation. The authors used logistic regression models to associate the probability of adequate sleep to school start time. Here are some adapted logistic regression results from this study: In(odds of adequate sleep) = 6, + B,, where x1 = school start time, measured as the number of minutes after 7 AM that the school starts. For this model, B,-0.014, SE(B,)-0.005. - What Is the estimated odds ratlo of adequate sleep, and 95% CI, for students who start at 8:30 AM compared to those who start at 7:30 AM? a. 1.01 (1.00, 1.02) b. 1.52 (1.13, 2.05) C. 2.32 (1.27, 4.22) d. 4.05 (1.49, 11.02)
In a study of 1991 model cars, a researcher computed the least-squares regression line of price (in dollars) on horsepower. He obtained the following equation for this line. Price = – 6677 + 175× Horsepower Based on the least-squares regression line, what would we predict the cost to be of a 1991 model car with horsepower equal to 200? If the actual cost of a 1991 car with 200 horsepower is $27500, what is the residual? Is the predictionan underestimate or an overestimate? What does the slope of 175 and y intercept of (0,-6677) mean in the context of the problem? The coefficient of determination is ?2=84%. Interpret in the context of the problem. Find the correlation and interpret.

a) What is the strongest independent variable for the model predicting self-control for respondents living in good neighborhoods? and living in bad neighborhoods? b) In every situation above, the standard errors for the model predicting self-control for respondents in good neighborhoods are lower than the standard errors predicting self-control for respondents in bad neighborhoods. What might be one reason why this might occur?
