Because the specific metals aren’t mentioned in this inquiry.
The educational guesses that we can propose is that:
1. The
hypothetical inquiry: There are existing metals for making pots that will cook
food much faster.
2. The
one-tailed alternative hypothesis: There are other metals for making pots that
will cook food much faster than the other metals.
3. The
one-tailed null hypothesis: All metals that are used in making pots will cook
food at an equal rate.
