A musical note like that produced with a tun- ing fork or pitch meter is a pressure wave. Table 1.19 gives fre- quencies (in Hz) of musical notes on the tempered scale. The pressure versus time tuning fork data in Table 1.20 were col- lected using a CBLTM and a microphone. (pictures added)
(a) Find a sinusoidal regression equation for the data in Table
1.20 and superimpose its graph on a scatter plot of the data.
(b) Determine the frequency of and identify the musical note
produced by the tuning fork.
