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 us.(ii) the national crime survey (ncs), which is based on in terviews with a nationwide probability sample of households. in 1992, 4.9% of the households in the ncs sample told the interviewers thev had experi- enced a burglary within the past 12 months. the same year, the fbi reported a burglary rate of 32 per 1,000 households, or 3.2%, for the us. as a whole. if the fbi's 3.2% figure is the true burglary rate for the population of us households in 1992, what is the probability that the national crime survey would obtain a result of 4.9% or more? you may assume that the ncs is based on a simple random sample of 50,000 households out of a population of 100 million households. what do you conclude?
