number of passengers using temperature. a) What best describes the relationship between temperature and the number of passengers? b) Use the above information to obtain a least squares regression equati c) Graphically display your results and interpret your findings d) Predict the number of passengers when temperature is at 45 degree e) For the pair of data (temperature= 42oF, passengers =173, what is the residual? f) Can you predict the number of passenger when temperature is 65 oF
The KCCA’s transportation department is interested in studying the relationship between the temperature and the number of passengers that ride the main bus line in order to better serve their customers. The manager recorded the temperature at the beginning of the hour, and then had a bus
driver record the number of passengers that boarded the bus throughout the hour. Their findings are listed below.
