7) First-born children tend to develop language skills faster than their younger siblings. One possible explanation for this phenomenon is that first-borns have undivided attention from their parents. If that explanation is correct, then it is also reasonable that twins should show slower language development that single children and that triplets should be even slower. Davis (1937) investigated this possiblity The following data are similar to what Davis found. The scores represent a measure of language skill (higher scores indicate better language skills) at age 3 for each child. Is there a difference in the language skills of single children, twins, and triplets? Use an e .05 and Tukey HSD for post-hoc tests. Single For this hypothesis test, what is: Triplet Child Twin 6 5 8 Step 1) H0: null hypothesis 4 7 6 10 7 3 6 H1: research hypothe 5 4 4 8 for at least one type dfBetween-Tre Step 2) Wthin-Tre Step 1) H0: null hypothesis SingleChild = Twin = Triplet H1: research hypothesis The language skills are different for at least one type of child (single, twin, or triplet) Step 2) dfBetween-Treatments dWithin-Treatments Step 3) Step 4) pa accept/reject Step 5) H0: null hypothesis accept/reject H1: research hypothesis Step 5B) Is there a significant difference in the language skill scores between Yes/No "Single Child" and "Twins"? Yes/No "Twins" and "Triplets "? Yes/No "Single Child" and "Triplets"?
