Two different technicians (Tech A and Tech B) each measured the cardiac output for a sample of 36 patients using Doppler Echocardiaography. The supervisor would like to use this paired data to assess inter-rater reliability by testing if the population mean difference in cardiac output is 0 (no difference on average) versus the alternative that there is a difference. The hypotheses to be tested are: H0: ?d = 0 versus Ha: ?d ? 0, using a 10% significance level.A. One QQ Plot of the sample of differences in measurementsB. One QQ Plot of the population of differences in measurementsC. Two QQ Plots, one for the sample of measurements by Tech A and one for the sample of measurements by Tech BD. Two QQ Plots, one for the population of measurements by Tech A and one for the population of measurements by Tech B
