Children of a certain age in the nation have an average weight of 86 with a variance of 92.16 lb. A complaint is made that children are overfed fed in a municipal children's home. As evidence, a sample of 24 children of the given age is taken from the children's home with an average weight of 89.65 lb. What can be concluded with an α of 0.05?
a) What is the appropriate test statistic?
---Select one--- (na, z-test, one-sample t-test, independent-samples t-test, or related-samples t-test)
b)
Population:
---Select one--- (children in the nation, children from the children's home, feeding method, children's home, or weight)
Sample:
---Select one--- (children in the nation, children from the children's home, feeding method, children's home, or weight)
c) Obtain/compute the appropriate values to make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =
Decision:  ---Select one--- (Reject H0 or Fail to reject H0)
d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[  ,  ]
e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and select "na" below.
d =  ;   ---Select one--- (na, trivial effect, small effect, medium effect, or large effect)
r2 =  ;   ---Select one--- (na, trivial effect, small effect, medium effect, or large effect)

f) Make an interpretation based on the results.

The weight of children in the children's home was significantly higher than the weight of children in the nation.The weight of children in the children's home was significantly lower than the weight of children in the nation.    The weight of children in the children's home was not significantly different than the weight of children in the nation.
