He made his first mistake in step 5. He used the statement he was trying to prove as a reason.

Answer:
The two distributions are each nearly symmetric.
Step-by-step explanation:
Symmetric distributions are those in which the data occurs in regular frequencies.
If we calculate the difference between the two standard deviations we find that it is only 0.022 which may be due to the physical or chemical properties of water or salt. So it lies within the same range and is almost symmetrical.
We cannot say that the distributions do not overlap on the same range of temperatures because they lie within the same range.
These two options are also incorrect as they are totally opposite of each other. Suppose the distribution of salt water boiling temperatures is left-skewed then the distribution of tap water boiling temperatures cannot be right-skewed as they have the same range and vice versa.
