Suppose we want to test the claim that the majority of adults are in favor of raising the vote age to 21. Is the hypothesis test
Fofino [41]

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.

scott is riding a bike course that is 50 miles long. So far, he has ridden 6 miles of the course. What percentage of the course
ad-work [718]

Scott has ridden 12% of the course.

Step-by-step explanation:

Length of bike course = 50 miles

Distance covered = 6 miles

Distance covered in percentage = \frac{Distance\ covered}{length\ of\ bike\ course}*100

Distance covered in percentage = \frac{6}{50}*100\\

Distance covered in percentage = \frac{600}{50}

Distance covered in percentage = 12%

Scott has ridden 12% of the course.

Keywords: percentage, distance
