Answer:

The data provide sufficient evidence that older people are more likely to be victimized.

Step-by-step explanation:

H 0 : P = 0.10

H 1 : P > 0.10 (Right tailed test)

n = 527, P = 0.1235

The test statistics

x = P - p / \sqrt{p*(1-p) / n}

x = 0.1235 - 0.10 / \sqrt{0.10 * 0.90 / 527}

x = 0.0235 / \sqrt{0.09 / 527}

x = 0.0235 / \sqrt{0.00017077798}

x = 0.0235 / 0.0130682049264618

x = 1.798257689731729

x = 1.798

P value = [1 - p(Z > 1.7980] (Right tailed test)

P value = 0.036089

The P - Value is very small, so <u>reject H0</u>

Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.

Which equation represents the line shown in the graph below?
likoan [24]

The answer is y=2x+5


To get it use point slope by taking two points and solving .


Slope formula


M= y2-y1/x2-x1


With two points


(0,5)(-5,-5)


M= -5-5/-5-0

M= -10/-5

M=2


2 is slope


Now get one of the points

(0,5) And slope to create equation y=mx+b . Now find b


5=2(0)+b

5=b


So now you can put it all together


Y= 2x+5
