In the u. s., there are two sources of national statistics on crime rates: (i) the fbi’s uniform crime reporting program, which publishes summaries on all crimes reported to police agencies in jurisdictions covering virtually 100% of the population; (ii) the national crime survey, based on interviews with a nationwide probability sample of households.
in 2001, 3% of the households in the sample told the interviewers they had experienced at least one burglary within the past 12 months. the same year, the fbi reported a burglary rate of 20 per 1,000 households, or 2%. can this difference be explained as chance error? you may assume that the survey is based on a simple random sample of 50,000 households out of 100 million households.

to answer this question, you use which of the following:
the one-sample z-test
the two-sample z-test
the t-test
the χ2-test, with a null hypothesis that tells you the contents of the box (goodness of fit)
the χ2-test for independence
correlation
regression
none of these

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
