(Data from observations of spilled drinks (ml) from sample cans carried out by 2 robots (A and B) are as follows: for robot A: an average of 13.2 and sample variance = 1.70 (nA=5 samples), while for robot B: the average is 10.67 and the sample variance is 1.47 (fnB= 6 samples). Assuming the two variances are the equal (01-02), then the combined variance value (sp²)) is: A. other B. sp^2=1,25 C. sp^2=1,570 D. sp^2 = 2,466
