Answer:

The hypothesis test is right-tailed.

Step-by-step explanation:

We are given that we want to test the claim that the majority of adults are in favor of raising the voting age to 21.

Let p = <u><em>proportion of adults who are in favor of raising the voting age to 21</em></u>

So, Null Hypothesis, H_0 : p \leq 50%

Alternate Hypothesis, H_A : p > 50%

As we know that the majority is there when we have more 50% chance of happening of that event.

Here, the null hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is less or equal to 50%.

On the other hand, the alternate hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is more than 50%.

This shows that our hypothesis test is right-tailed because in the alternate hypothesis, the greater than sign is included.

A fair coin is tossed 5000 times. What can you say about getting the outcome of exactly 2500 tails
WINSTONCH [101]

Step-by-step explanation:

You can't expect to get exactly 2500 out of 5000 tosses more than a few times . You will come pretty close, but that's only good in horseshoes.

Of course I'm answering this on the basis of a computer language and not actually performinig this a million tmes, each part of a million consisting of 5000 tosses.

Simulations and not completely unbiased, but based on experience, 5000 is a very small number and getting 2500 more than a couple of times is unlikely

Round 392 to the nearest ten
Bezzdna [24]
Nearest 10 is according to the last digit.
if the digit is >5, it +1 to the tenth digit. If it's <5, it will be reduced to 0.

for your case, 392, 2 < 5, therefore rounded up to nearest tenth is 390.

Will mark brainliest!!!
Savatey [412]

Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

  • We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

  • 4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

  • 12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0
