2.37 The output of an instrument is often a waveform. With the goal of developing a numerical measure of closeness, scientists asked 11 experts to look at two waveforms on the same graph and give a number be- tween 0 and 1 to quantify how well the two wave- forms agree. The agreement numbers for one pair of waveforms are 0.50 0.40 0.04 0.45 0.65 0.40 0.20 0.30 0.60 0.45 (a) Calculate the sample mean x. (b) Calculate sample standard deviation s. 2.37 The output of an instrument is often a waveform.
