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

We know that
<span>the Consumer Price Index
(CPI) is equals to
</span>CPI=100*[cost of the pizza today/cost of the pizza <span>in the base year]
[</span>cost of the pizza in the base year]=100*[cost of the pizza today/CPI]
cost of the pizza today=$12
<span>CPI=200
so
</span>[cost of the pizza in the base year]=100*[12/200]-----> $6
<span>
the answer is
</span>The cost of the pizza in the base year is $6<span>
</span>
