Expert Solution
Solution:
At 95% confidence level the 
is ,
= 1 - 95% = 1 - 0.95 = 0.05
/ 2 = 0.05 / 2 = 0.025
/2,df =
0.025,11 = 21.920
and
1-
/2,df =
0.975,11 = 3.816
2L
=
2/2,df
= 21.920

Deuterium (Subscript 1 Superscript 2 Baseline H) is an
attractive fuel for fusion reactions because it is abundant in the
waters of the oceans. In the oceans, about 0.0177% of the hydrogen
atoms in the water (H2O) are deuterium atoms. (a) How many
deuterium atoms are there in one kilogram of water? (b) If each
deuterium nucleus produces about 7.20 MeV in a fusion reaction, how
many kilograms of ocean water would be needed to supply the energy
needs of...
