Speed of sound data

Data from laboratory 092 where echo flight times are used to determine the speed of sound.

Experimentally estimated speed of sound:    225.65 m/s
Linear estimate with y-intercept forced to zero:  281.13 m/s
Theoretic sound speed based on temperature and relative humidity:    348.00 m/s.
Error for slope calculation:   -35.16%
Error for linear estimate with y-intercept forced to zero:    -19.22%
Correlation:   0.82
