Unformatted text preview: 2.69 # of measurements between μσ and μ+σ 36 36 37 Analysis: Trial 1 and 3 agree within their errors (665±3.39 is within 664±2.69), but the Trial 1 and 3 means are more than 7 errors away from the Trial 2 mean. Trial 1: (μ)^(.5) = 25.8 this value is very close to σ = 25Trial 2: (μ)^(.5) = 26.3 this value is very close to σ = 24Trial 3: (μ)^(.5) = 25.8 this value is somewhat close to σ = 19 We can also see that the distribution of nvalues resembles a Gaussian distribution in each of the three trials, as is evidenced by the histograms of the nvalues. In trials 1, 2 and 3, the percentage of the nvalues that fell within the standard of deviation were 72%, 72% and 74% respectively. These percentages all agree with the predicted 68.3% of values that fall within σ of the mean in a gaussian distribution....
