Question

Please provide right answers for the wronged parts of this questions.

Children of a certain age in the nation have an average weight of 85 with a variance of 98.01 Ib. A complaint is made that children are underfed fed in a boarding school. As evidence, a sample of 25 children of the given age is taken from the boarding school with an average
weight of 90.13 Ib. What can be concluded with a = 0.01?
a) What is the appropriate test statistic?
z-test
