Download the full data set of measurements of cockpit noise level for a commercial jet airliner from the McGraw-Hill Connect® website (only six data values are shown).

(a) Use Excel to make a scatter plot, placing Airspeed on the X-axis and Noise Level on the Y-axis. Add titles and modify the default colors, fonts, etc., as you judge appropriate to make the scatter plot effective.

(b) Describe the relationship (if any) between X and Y. Weak? Strong? Negative? Positive? Linear? Nonlinear?
