Using curved parentheses (not square brackets) and * for multiplication and / or ÷ for division, a Google or Bing search box will evaluate such expressions for you according to the Order of Operations.
_____
2[(14 -3) + (4 x 4 x 4) /4] - 2.5 x 12
= 2((11) + 64/4) - 30 . . . . . evaluate inside inner parentheses, to final multiplication
= 2(11 +16) - 30 . . . . . division before addition
= 2·27 -30 . . . . add inside parentheses
= 54 -30 . . . . . .multiplication before addition
= 24

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 /
x = 0.1235 - 0.10 /
x = 0.0235 /
x = 0.0235 /
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.
