Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13
Hope this Helps!!!
For every decimal place you move a decimal through a number you can think of it as multiplying or dividing by ten.
take for example 1000.0
if you move the decimal to make this number 100.00 you divided it by ten
if you move the decimal again to make 10.000 you divided ten again
but, if you make the number bigger, say 10000. then you have multiplyed by ten.
Answer:
Cool
Step-by-step explanation:
D.
or divide 900 by 20 and see the closest
Step-by-step explanation:
=n2-11n+18
=n2-(9+2)n+18
=n2-9n-2n+18
=n(n-9)-2(n-9)
=(n-2)(n-9)
