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.

Complete the table for the given rule. Rule: y=X/4(fraction)
Lady_Fox [76]

Answer:

\large\huge\boxed{\begin{array}{c|c}x&y\\\\4&1\\\\2&\frac{1}{2}\\\\9&\frac{9}{2}\end{array}}

Step-by-step explanation:

y=\dfrac{x}{4}

Put the values of x from the table to the equation:

x=4\to y=\dfrac{4}{4}=1\\\\x=2\to y=\dfrac{2}{4}=\dfrac{2:2}{4:2}=\dfrac{1}{2}\\\\x=9\to y=\dfrac{9}{4}

From the comment.

Convert the equation:

y=\dfrac{x}{4}    <em>multiply both sides by 4</em>

4y=x\to x=4y

Put the values of y from the table to the equation:

y=4\to x=(4)(4)=16\\\\y=2\to x=(4)(2)=8\\\\y=9\to x=(4)(9)=36

\large\huge\boxed{\begin{array}{c|c}x&y\\\\16&4\\\\8&2\\\\36&9\end{array}}

djyliett [7]

Answer:

$32,400

Step-by-step explanation:

We can just replace 12 for x in the equation y = 2700x

y = 2700x

y = 2700(12)

y = 32,400

The money paid after 12 years is $32,400
