This exercise is to be solved using program R.
Information about worms that inhabit various conditions was
obtained (Worms.txt). Suppose that the mean of Worm.density is 5,
then you want to conduct a statistical test. (H0: mu=5 vs H1:
mu≠5)
Find t statistics.
Compare t statistics with t distribution table and conclude
with a significant level of 5%.
Show the code and Rhistory.
