Question

1. A researcher wanted to learn whether emotional stability of home schooled children is different from the emotionality of children in general. The US government reports that all children (age 10) had an average score 30 on the Emotional Stability Test with a higher score meaning that an individual is more stable. The following scores were gathered from 9 randomly selected home schooled children (age 10): 28, 25, 25, 22, 30, 27, 27, 32, 27. Use a single-sample t-test to determine the outcome.

   In the box below, provide the following information:

   Null Hypothesis in sentence form (1 point):

   Alternative Hypothesis in sentence form (1 point):

   Critical Value(s) (2 points):

   Calculations (4 points): Note: the more detail you provide, the more partial credit that I can give you if you make a mistake.

   Outcome (determination of significance or not, and what this reflects in everyday language, 2 points)
