The data is based on data from a physical science experiment performed by the SC 130 students that 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 SE.
The theoretic value for the speed of sound on the day of the experiment was 348 m/s.
Given the following hypothesis:
Null hypothesis: H0: μ = 348
Alternate hypothesis: H1: μ ≠ 348
Use α = 0.05
tc = ________________Calculate the tcritical for α = 0.05
t = _____________ Calculate the t-statistic t.
____________________ Based on the values of tc and t, should you fail to rejectORreject the null hypothesis?
_____________ Does the sample data support a possible population mean sound speed of 348?
The hypothesis test result should agree with a 95% confidence interval result!
