here's the entire problem please show steps with formulas so I can follow

1. First born children tend to develop language skills faster than their younger siblings. One possible explanation for this phenomenon is that rst-horns have undivided attention from their parents. If this explanation is correct, then it is also reasonable that twins should show slower language development than single children and that triplets should be even slower. The following hypothetical data demonstrate the relationship. The dependent variable is a measure of language skill at age 3 for each child. Single child Twin Triplet 8 6 5 7 4- 5 10 6 8 6 7 3 9 4- 5 8 9 4- a. Use an ANOVA with on = 0.05 to determine whether there are any significant mean differences among the three groups of children. HINT: N = 18; G = 114-: EXZ = 792. You will have to gure out T (group totals) and SS [sum of squares for each group]. Group totals (T) for each group [0.5pts) Sum of Squares (SS) for each group (0.5pts) Null and alternative hypotheses [1pt) Shade critical region on distribution and place an asterisk [*) on the distribution where F-ratio is located [1pt] make a decision to either reject or fail to reject null hypothesis [1pt) write a conclusion sentence that describes the nding in words AND lists the supporting statistical statement [1pt] completed summary table.
