The following information was obtained from matched samples taken from two populations. Assume the population of differences is normally distributed. Individual Method 1 Method 2 1 7 7 2 5 7 3 6 4 4 7 8 5 5 9 The point estimate of the difference between the means of the two populations (Method 1 - Method 2) is -1 and the standard deviation is 2.24. The null hypothesis tested is Ho: Hd = 0. Find the tes statistic for the difference between the two population means. 0-2 O-1 O O 0 2.
