autosave questio Consider a train that runs from Seattle to Los Angeles The mean travel time from one stop to the next is 130 minutes with a standard deviation of 114 minutes The mean distance traveled from one stop to the next is 108 miles with a standard deviation of 100 miles The correlation between travel time and distance is 0 631 Travel Time minutes 360 300 240 180 120 60 100 Assignment Responses submit dep 300 200 Distance miles a Write the equation of the regression line for predicting travel time Let y represent travel time minutes and let x represent distance traveled in miles b Interpret the slope in this context For each mile increase in distance traveled we would expect travel time to increase on average by Interpret the intercept in this context When the distance traveled is 0 miles the travel time is expected to be on average minutes minutes c Calculate R2 of the regression line for predicting travel time from distance traveled for the train Round your answer to three decimal places R Interpret R2 in the context of the application Give your answer as a percent Round your answer to one decimal place Approximately of the variation in travel time is accounted for by the model The distance between Santa Barbara and Los Angeles is 103 miles Use the model to estimate the time in minutes it takes for the train to travel between these two cities Round your answer to the
