In the iris data, we wish to build a simple linear regression model to predict Sepal. Length based on Petal. Length. Calculate the least squares regression line to predict Sepal. Length based on Petal. Length. Interpret the slope of the line in the context of the problem. Remember that both variables are measured in centimeters.

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
