A car enthusiast was interested in studying cars from 1974. He collected data out of a 1974 US edition of Motor Trend magazine. He computed a simple linear regression equation to predict the miles per gallon (mpg) of an automobile based on the horsepower (hp). Interpret the slope (if applicable).  

q10.png Consider the figure below. Which of the following congruence statements is appropriate?

A 95% confidence interval for the slope is (0.70, 1.19). What can be concluded?

A simple linear regression equation was created to predict internet use per country in 2024 based on 2015.  The model was yhat = 36.42+0.75x.  The 95% confidence interval for Bulgaria was (76.9, 78.88).  Interpret the confidence interval. 

Suppose segment CD is a perpendicular bisector of segment AB, and the two segments intersect at point P. Which of the following must be true?

A banker was interested in studying the probability of default for businesses in Florida in the Real Estate, Rental, and Leasing sectors of business. We will be using a data set of 898 loans from Florida.  Below is the R output from the logistic regression model.  The x variable is urban. Urban is 1 if the property is an urban area and 0 otherwise. What is the test statistic for the following hypothesis: Ho: 

What is the method that finds the multiple regression equation?

Brooke wants to estimate the house prices of houses in Gainesville in August 2020 using square footage, lot size, and distance from ES.  Which of the following is the best interpretation of the slope coefficient for BATHS (125,877.5)?

The GINI is a measure of inequality in a society. A higher number means that there is more inequality in a society. A scatterplot of the GINI score for 2018(y) compared to 1940(x) for 195 countries was made. (Data from the Gapminder website.)   Describe the scatterplot by matching the descriptions below.
