Students in SC 130 Physical Science measured the speed of sound by measuring the distance and duration of flight for a sound based on the time delay of the arrival of the echo. Teams recorded and calculated twenty-five different sound speeds recorded in the table.

The actual speed of sound that day was 348 m/s. Is 348 m/s a possible speed of sound based on the 95% confidence interval for the experimental measurements?
