Guilty verdicts in court cases a reporter on cnn. com stated in july 2010 that 95% of all court cases that go to trial result in a guilty verdict. to test the accuracy of this claim, we collect a random sample of 2000 court cases that went to trial and record the proportion that resulted in a guilty verdict. state the null and alternative hypotheses. your answer should be an expression composed of symbols: ミ夭< . > , μ, μ1-12-р, p1-p2, 0.95, rho, p, p1-p2

Step-by-step explanation:

Null hypothesis : Its a statement of equality that claims that there is no significant difference between the groups being tested.

Alternative hypothesis : Its a statement of inequality that claims that there is  significant difference between the groups being tested.

Given : A reporter on cnn.com stated in July 2010 that 95% of all court cases that go to trial result in a guilty verdict.

Let p be the parameter that denotes the population proportion of all court cases that go to trial result in a guilty verdict .

Then, the the null and alternative hypotheses for the given situation will be :

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
