Question:
2.A researcher proposes that there will be a significant difference in growth outcomes among in-school children receiving one special meal a day in a particular school compared with those buying food from food vendors proceeded to conduct an experiment to test the research hypothesis by collecting growth outcomes of BMI from sample of school children from three schools representing those receiving the specially prepared meals (Group A); those buying meals from food vendors at school (Group B) and children bring food from home(Group C). With the data collected below, 1. would you say that the researcher is correct in making the claim that there will be a significant difference in growth outcomes among in-school children receiving one special meal a day in the school compared to those buying food from food vendors and bringing food from home? (Assume BMI is normally distribute in the population and the Critical Table F-value for df(2,15)is 3.682)
Group A | 10 | 16 | 9 | 12 | 15 | 13 |
Group B | 8 | 10 | 6 | 13 | 16 | 11 |
Group C | 11 | 13 | 13 | 5 | 15 | 12 |
