Question
Researchers wanted to compare the overall nutrient intake of children (ages 2 to 19) who exclusively use skim milk instead of 1%, 2%, or whole milk. The researchers combined children who consumed 1% or 2% milk into a "mixed milk" category. The accompanying data represent the daily calcium intake (in mg) for a random sample of eight children in each category. Complete parts (a) through (b).
a. what is the p- value
(b) If the null hypothesis is rejected in part (a), use Tukey's test to determine which pairwise means differ using a familywise error rate of =0.05. Calculate the test statistic q0 for each pairwise difference.
