A researcher knows that "maternal attachment" (MA) scores of 18 month old toddlers who were breastfed is normally distributed with = 7.5 and = 1.2. High scores indicate greater maternal attachment with the MA test; the maximum score is 10. She speculates that 18 month old toddlers who are not breastfed will differ in terms of their MA scores from those who were breastfed. With a sample of N = 20 non- breastfed toddlers, the researcher obtained the MA scores below.

MA scores of non- breastfed toddlers: 8, 5, 4, 3, 7, 2, 3, 7, 9, 4, 6, 8, 2, 8, 8, 9, 6, 7, 7, 5

With= .01, complete step 4 of the hypothesis testing procedure, what decision and conclusion should the researcher make?

Group of answer choices

The researcher should retain H0and conclude toddlers who are not breastfed do not differ in terms of their MA scores from those who are breastfed

The researcher should retain H0and conclude toddlers who are not breastfed differ in terms of their MA scores from those who are breastfed

The researcher should reject H0and conclude that there is a positive correlation between breast feeding and maternal attachment

The researcher should reject HAand conclude toddlers who are not breastfed do not differ in terms of their MA scores from those who are breastfed

The researcher should reject H0and conclude toddlers who are not breastfed differ in terms of their MA scores from those who are breastfed
