A person who claims to be psychic says that the​ probability, p, that he can correctly predict the outcome of the value of of a

card drawn from a deck of cards in another room is greater than 1 divided by 13​, the value that applies with random guessing. If we want to test this​ claim, we could use the data from an experiment in which he predicts the outcomes for n trials. State hypotheses for a significance​ test, letting the alternative hypothesis reflect the​ psychic's claim.

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}.

I NEED HELP ASAP!!!<br><br> Find the measure of angle A using the image below:
Andreyy89

Answer:

A = 125º

Step-by-step explanation:

Missing angle is the supplement of 157.5

180 - 157.5 = 22.5

----------------------------

Sum of angles in triangle is 180

22.5 + (-10x) + (-x + 20) = 180

Combine like terms

-11x + 42.5 = 180

Subtract 42.5 from both sides

-11x = 137.5

Divide both sides by -11

x = -12.5

---------------------------

A = -10(-12.5)

A = 125º

Quickly please im very confused
deff fn [24]

Answer:

A: -16/3

B: 16/3

C: -6

D: -6

E: 6

Step-by-step explanation:

A would be -16/3 because you multiply -2 time 8 which is 116. And the denominator is 3.

B would be 16/3. It is the same as problem A but there are two negatives which make positive.

C is -6. You just divide -18/3.

D is the exact same as C. It just has parenthesis but the answer is still -6.

E is 6 because there are two negatives which make a positive.
