s is the typical amount by which the (BMI Change, Depression Score Change) value what is predicted using the least squares regression line. A paper gives data on x = change in Body Mass Index (BMI, in kilograms/meter2) and y = change in a measure of depression for patients suffering from depression who participated in a pulmonary rehabilitation program.

true or false. Explain In a fixed effects regression, the residuals (ûit) will be uncorrelated with the estimated fixed effects.
1. A. A biologist claims that in a certain hybridization experiment, ¼ of the peas produced would have yellow pods. In an experiment to test this theory, 158 of 580 peas had yellow pods. Does this result cause doubt on the correctness of the biologist's theory? Test at the a = 0.05 level. Use the p-value approach. Test of Hypothesis: Diagram: Test statistic to three decimals: p-value: Rejection rule: Conclusion in technical terms and in the words of the problem:

A team from UNHABITAT took a random sample of 230 households in a city to better understand how the size of a house (measured in metres) is related to the number of people living in that house. They performed a regression analysis on the data and found that regression model had an R² = 18.3%. What is the correlation between the size of a house and the number of people living in that house? 0.667 0.183 0.033 0.904 0.428

Forensic scientists can learn about events at a crime scene by collecting data. Ex: Properties of glass shards at a crime scene such as chemical composition can indicate what type of glass was broken at the scene. Possible types include building glass (building windows or doors), vehicle glass (car windows or doors), or household glass (lightbulbs, baking dishes). The fitted logistic regression model for predicting whether a glass shard is building glass based on sodium is: = 20.02+(-1.42) (sodium) 1+e20.02+(-1.42) (sodium) Calculate the log-odds that a glass shard with sodium = 13.08 is building glass. Ex: 1.23 C Calculate the probability that a glass shard with sodium = 13.08 is building glass.
The weight (in pounds) and height (in inches) for a child were measured every few months over a two-year Using technology, what is the slope of the least-squares regression line and what is its interpretation? period. The results are given in the table. The slope is 1.98, which means for each additional 35 inch in height, the child's weight will increase by 1.98 Weight (x) 8. 12 18 24 30 32 37 40 30 32 33 36 38 pounds. Helght (v) 22 23 26 35 The slope is 1.98, which means for each additional inch in height, the child's weight is predicted to increase by 1.98 pounds. The slope is 0.50, which means for each additional pound in weight, the child's height will increase by 0.5 inches. The slope is 0.50, which means for each additional pound in weight, the child's height is predicted to increase by 0.5 inches.
Explain Which of the following statements are true about studentized residuals? They are the deviations of the observed values from the fitted line. They're closely related to the errors of prediction of the observation. Large studentized residuals will lead to large influence on the regression model in all circumstances
