Full data set S Children\'s cereal: 41.9, 55.8, 46.3,42.9, 51.2,46.1, 52.5,41.2,42.2,42.6,49,41, 36.2, 56.3,46, 54.8, 39.8, 59.1,43.8, 32.6 Adults\' cereal: 21.8, 26.5, 3, 9.8, 3.3,24.3, 17.1,11.1,24.3, 8.8, 5.9,10.2, 19.9,13.5,2.3, 18.4, 1.5,1.7,0.3, 8.5,10.7, 0.5, 0.8, 0.9, 8.2,1,19.3, 8.6,19.9,14.8 Write the null and alternative hypotheses. Let group C correspond to children\'s cereals and group A correspond to adults\' cereal h0:mu c-ma 0 h0: mu c-ma =0 ha mu c-ma = 0ha; mu c-ma >0 H0: mu c-ma

Solution

B)

Ho : miu C - miu A = 0

H1 : miu C - miuA > 0

because the food company is concerned about the crtiicim of sugars in children\'s cereals so that means that the difference will be positive if that is real
