The Peabody Picture Vocabulary Test has a standard score mean of 100 and a standard deviation of 15. You tested a class of grade 2 students wonderinf if these scores would be different from the population. After testing this hypotheses you decided to continue looking at this data to determine if there are any group differences based on birth order. You group the children the on whether they are the oldest chlid, middle child, or the youngest child. Here is the data based on grouped information. Oldest child: 87 84 98 104 106 91 96 92 Middle child: 65 74 62 60 73 64 71 78 Youngest child: 115 84 85 83 95 94 108 102 89 Test the hypotheses at (alpha=0.05) level of signifance using the 5 step procedure.Make sure to clearly state the null and alternative hypotheses.Round your answer to 2 decimal. You are encouraged to use the following table to help you with your calculation.

The Peabody Picture Vocabulary Test has a standard score mean of 100 and a standard deviation of
15. You tested a class of grade 2 students wonderinf if these scores would be different from the
population. After testing this hypotheses you decided to continue looking at this data to determine
if there are any group differences based on birth order. You group the children the on whether they
are the oldest chlid, middle child, or the youngest child. Here is the data based on grouped information.
