Fifty (50) technicians were given a 1000 g weight to measure to evaluate a new scale. The mean of their measurements was x-bar=1000.6 grams. The scale has a known standard deviation of 2 grams. Do the technicians measurements differ from 1000 grams? Use the 5% significance level. |Enter the ALTERNATIVE HYPOTHESIS, H1 number. ______________________________ Note: Enter INGEGER 1, 2 or 3, No decimal for selection: 1) H1: mean > 1000 2) H1: mean < 1000 3) H1: mean Not Equal To 1000
