The results of a published research study indicated that babies fed on breast milk gained an average of 11 ounces per week; babies fed a powdered instant baby formula gained an average of 2 ounces per week. The nurse researcher reported that the t-test statistic was t = 4.6 (p = 0.001 [alpha = 0.05]). The nurse reading this information should make which decision about using this research evidence to try to get more mothers to breastfeed their babies?

A. The information should not be used because there is no evidence about a real difference in weight gain.

B. The information should not be used because the amount of weight gain was not clinically significant.

C. The information should be used because breast feeding has been proven to be superior to any use of formula.

D. The information should be used because the amount of weight gain was statistically and clinically significant.
