Answer:
The required null and alternative hypothesis are 
and 
.
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 .

Ms. Cassidy instructed Miguel to change one sign of the graph of y < 2x – 4 so that point (2, 3) can be included in the solution set.
To check which of the given options might Miguel write we check the inequality that holds true for the point (2,3).Substituting x=2 ,y=3 we have:
1) y < 2x – 1
3<2(2)-1
3<3 Not True.
2)y ≤ 2x – 4
3≤ 2(2) -4
3≤ 0 .Not true.
3) y > 2x – 4
3> 2(2)-4
3> 0 True.
4) y < 2x + 4
3<2(2)+4
3<8 True
5) .y < 3.5x – 4
3< 3.5(2)-4
3<3 Not true
6) y < 4x – 4
3<4(2)-4
3<4 True.
Options 3 ,4 ,6 holds true for the point (2,3)
Answer:
D. increase of $1 in advertising is associated with an increase of $6,000 in sales.
Step-by-step explanation:
Every dollar in advertisting is multiply by 6 in the equation, but every unit in y represent $1000. That means that $1 1n advertisting is multiply by 6 and then by $1000, that is $1 in advertisting = $6000 in sales.
