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 $H_{1}:p < 0.081$ .

Find the value of x and thank for answer

lakkis [162]

The value for x is 102 degrees

First we can find the second value in the triangle by subtracting 141 from 180. This works because when added together these two angles come together to from a line (180 degrees) because this value is now known (39 degrees) we can subtract both from 180:

180-39-39= x = 102
