The data is based on data from a physical science experiment performed by the SC 130 students in the 8:00 section spring 2012. The students measured the experimental speed of sound. Two pieces of wooden board were clapped to produce a sound that generates a distinct echo off of distant buildings. The flight time of echoes was measured at seven different locations. Each location involved a different distance from a building. The sound speeds measured are in the table.

n = _________ Calculate the sample size n.
x = _________ Calculate the sample mean x.
sx = _________ Calculate the sample standard deviation sx.
SE = _________ Calculate the standard error of the mean.
E __________ Calculate the margin of error E of the mean.
p(__________ ≤ μ ≤ __________) = 0.6827
Calculate the 68.27% confidence interval for the sample mean.
_________ The theoretic value for the speed of sound in the 8:00 section was 347 m/s. Is the theoretic value of 347 m/s within the 68% confidence interval?
