... Again, due to symmetry, multiplication by two yields the probability that x lies within two standard deviations from the mean value, either to the right or to the left. Since 2(0.4772) = 0.9544, we are 95.44% confident that x lies within two standard deviations (on either side) of the mean. Since 95 ...

... (d) Sample speeds for a random sample of 23 vehicles are measured at this location, and the sample mean is 66 mph. Given the answer to part (c), explain whether this result is consistent with the belief that the mean speed at this location is µ = 60 mph. 5. Small planes cannot fly well if the payloa ...

... We use results from probability and statistics as a way of indicating how “good” a measurement is. The most common quality indicator is relative precision. Relative precision = [uncertainty of measurement]/measurement Uncertainty in measurement is usually square root of variance: = standard deviat ...
