The dataset Silverweight .csv contains data collected "The Absolute Isotopic Abundance and Atomic Weight of a Reference Sample of Silver" from NBS Journal of Research, 87, pp. 9-19. It compared the Atomic weight of silver (in Aus) as measured by 2 different instruements. (a) Perform a hypothesis test to determine if their is evidence for the existence of bias or improper calibration in one of the instruments, use a = 0.01. (b) Construct a 99% confidence interval for the difference in the estimated atomic weights. (c) Evaluate the assumptions of your hypothesis test in a). (d) Compute an appropriate effect size for the difference in estimates between the two techniques. (e) Estimate the difference in calibrations (effect size as measured as difference of the means) that you have a 90% chance of detecting for this dataset. Use sp = 1.7 x 10-5 Au of the sample as approximately equal to o and a sample size of 24 in each group. - (f) What sample size would you need in order to have an 80% chance of detecting a calibration erence of 0.8 x 10-5 Au between the two machines. (g) Construct a plot to show the mean silver weight measured on both instruments.
