A statistics professor wants to use thenumber of hours a student studies for astatistic final exam (x) to predict the finalexam score (y). A regression model was fitbased on data collected for a class duringthe previous semester, with the followingresults: y =35.0 + 3xWhat is the interpretation of the y-intercept?Select the correct response:The y-intercept indicates thatwhen the student study for thefinal exam, the mean final examscore is highThe y-intercept indicates thatwhen the student does not studyfor the final exam, the mean finalexam score is 35.0The y-intercept indicates that foreach increase of one hour instudying time, the mean change inthe final exam score is predictedto be 3.0The y-intercept indicates that foreach increase of one hour instudying time, the mean change inthe final exam score is predictedto be 38.

Given equation represent the relationship between final score ans study time.

A statistics professor wants to use the number of hours a student studies for a statistic final exam (x) to predict the final exam score (y). A regression model was fit based on data collected for a class during the previous semester, with the following results: y =35.0 + 3x Which of the following is the correct interpretation of the regression coefficient (slope)? Select the correct response: When the student does not study for the final exam, the mean final exam score is 35.0. None of the above are an interpretation of the slope For each increase of one hour in studying time, the mean change in the final exam score is predicted to be 35.0 For each increase of one hour in studying time, the mean change in the final exam score is predicted to be 3.0.

An e-commerce retailer was trying to understand how customer engagement correlates to customer purchases. They built the following regression model: Probability of Purchase = 0.1619 + 0.07 Emails Opened. If someone opens 5 emails how likely are they to purchase? If someone has a 75% chance of purchase how many emails have they opened? If someone opens no emails how likely are they to purchase? What is the slope here and what does it tell us?
