The average mean speed in miles per hour and length of flight in miles were recorded for 27 airline flights. The scatterplot of these data is shown below with flight length in miles on the x-axis (ranging from 0 to 5000) and average speed in miles per hour (ranging from 350 to 550). Average Speed (mph) 550 500 450 400 350 0 Scatterplot for 27 Airline Flights 1000 2000 3000 Flight Length (miles) 4000 5000 We see the graph starts with the dots around (100, 370) and increases to about (1500, 500). Then continues to about (5000, 550). Is it appropriate to run a linear regression t-test for the slope?
