A series of four measurements of the ratio of the circumference to diameter of a disk are made. The results of these measurements are: 3.140, 3.133, 3.132, 3.133. The average of the four measurements is the experimental value for Pi-Lab and the accepted value is Pi = 3.141. What is the percent error of these measurements? a) 1 % b) 2% c) 0.5% d)0.2%
A local police department attempted to estimate the average rate of speed of vehicles along a strip of Main Street. With hidden radar, the speed of a random selection of 35 vehicles was measured, which yielded a 2 sample mean of 45 mph and a standard deviation of 5 mph. Find the 99% confidence interval for the population mean. Write a concluding statement.
The calibrated length of a baseline is 402.267 m. A mean observation for the distance is 402.251 m with a standard deviation of ±0.0052 m after 6 readings with an EDM. a. Is the observed distance statistically different from the calibrated length at a 5 percent level of significance? b. Is the observed distance statistically different from the calibrated length at a 10 percent level of significance?
