.
Step-by-step explanation:
Consider the provided information.
A person who claims to be psychic says that the probability, p, that he can correctly predict the outcome of the value of a card drawn from a deck of cards in another room is greater than 1/13, the value that applies with random guessing.
To test this claim we need to use the data from an experiment in which he predicts the outcomes for n trials.
Since, alternative hypothesis represents the effect and null hypothesis represents no effect,
Therefore null hypothesis will be: The person can predict outcome of the value of a card drawn in another room 1/13. 
The alternative hypothesis will be the person can predict outcome of the value of card is greater than 1/3. 
Hence, the required null and alternative hypothesis are
and

The volume of the tank is,
12×20×15+40×(50-15)×12
= 3600+16800
=20400 cubic meters
For each cubic meter, it costs $3.20, so for 20400 cubic meters it'll cost,
