The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are
USPshnik [31]

The appropriate hypothesis which is used to test the dropout rate are H_{0}:p > =0.081\\ and H_{1}: p < 0.081.

Given Drop out rate through 24 year old who are not enrolled is 8.1%, sample size=1000 and we have to find the hypothesis to test the drop out rate of the school.

The variable which needs to be studied is X=Number of individuals with age between 16 and 24 years old that are high school dropouts.

The parameter of interest is the proportion to high school drop outs is p.

Sample proportion=p^{1}=0.065

The hypothesis can be formed as under:

H_{0}:p > =0.081  (null hypothesis)

H_{1}:p < 0.081      ( alternate hypothesis)

Null hypothesis is a hypothesis which is tested for its validity and alternate hypothesis is hypothesis which is opposite of null hypothesis means if null hypothesis is rejected then the alternate hypothesis will be true.

Z_{H_{0} }=(p^{1}-p)/\sqrt{p*(1-p)/n}

=0.065-0.081/\sqrt{(0.081*0.0919)/1000}

=-1.85

Hence the appropriate hypothesis  are H_{0}:p > =0.081 and H_{1}:p < 0.081.

A line is parallel to y = 2x – 8 and
Naya [18.7K]

Answer:

y=2x+7

Step-by-step explanation:

When an equation is parallel to another, it shares the same slope.

Our original line is y=2x-8, and it is in slope-intercept form (y=mx+b)

This means that our slope is 2 because m represents the slope.

The slope of our parallel line will then also be 2.

<u>We can begin to plug that into point-slope form which is:</u>

y - y1 = m(x - x1)

This is where (x1, y1) is a point the line intersects, and m is the slope.

<u>Plugging in the slope, we'll have:</u>

y - y1 = 2(x - x1)

We also know it intersects the point (-4, -1)

We can plug this into our equation as well.

y - (-1) = m(x - (-4))

y+1=2(x+4)

<u>Now, we can simplify it into slope-intercept form:</u>

y+1=2(x+4)

Distribute

y+1=2x+8

Subtract 1 from both sides

y=2x+8-1

y=2x+7
