In a random sample of 40 boys (18 month old boys) it was determined their
average weight was 15.5 pounds with standard deviation of 1.5 pounds.
Using alpha level of 0.02, give a full solution (including labeling Step 0 thru
Step 5 as shown in class examples) including full calculator syntax that
tests whether the mean of all 18month old boys exceeds 15.0 pounds.
Must use pvalue method.
Again, need all steps labeled like this (you can copy and paste if that is
helpful)
Step 1 must be state each competing hypothesis as mathematical
statement with the correct symbols used (as shown in the class examples).
and do not forget full calculator syntax is required in step 3 , including the
TWO relevant outputs and ALSO must give the test statistic done by hand
with proper label as well (calculator syntax alone is not going to see credit if
ALSO the student did not include the test statistic done by hand).
