Yuki888 [10]

Answer:

The required null and alternative hypothesis are H_0=\frac{1}{13} and H_a>\frac{1}{13}.

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.  H_0=\frac{1}{13}

The alternative hypothesis will be the person can predict outcome of the value of card is greater than 1/3.  H_a>\frac{1}{13}

Hence, the required null and alternative hypothesis are H_0=\frac{1}{13} and H_a>\frac{1}{13}.

RUDIKE [14]

Answer:

Option A, $65,280

Step-by-step explanation:

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,

20400×$3.20

= $65,280
