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
