Of those, 85 mothers have been breast-feeding 6 months or longer, while 65 have not. (a) Find the expected counts for those who breast-fed 6 months or longer and for those who breast-fed less than 6 months. breast-fed less than 6 months breast-fed 6 months or longer (b) The null hypothesis for the chi-square goodness-of-fit test comparing observed percentages versus expected percentages of those who breast-fed 6 months or longer and those who did not Is which of the following? O Ho: P1 = 0.49 and P2 = 0.51 O Ho: P1 = 0.49 and P2 = 0.30 O Ho: P1 = 0.49 and P2 = 0.79 O Ho: P1 = 76.5 and P2 = 73.5 (c) Find the value of the chi-square test statistic for this scenario. (Round your answer to two decimal places.)
