$3\mathrm{.}31$ Download from the McGraw$-$Hill Connect$$ website the full data set of measurements of cockpit noise level for an older commercial jet airliner $($only the first $2$ and last $2$ 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? Hint: You may need to rescale the X and Y axes to see more detail.

Note: The decibel $($dB$)$ is a logarithmic unit that indicates the ratio of measured sound pressure to a benchmark. Some familiar examples for comparison: Vuvuzela horn at $1$ m $(120$ dB$),$ jack hammer at $1$ m $(100$ dB$),$ handheld electric mixer $(65$ dB$).$
