Document Summary

As in exercise 3, except it is desired to find the chance (approximately) that the total gross income of the audited forms is over ,000,000. Work parts (a) through (d); then find the chance (e) or explain why you need more information. The census bureau is planning to take a sample amounting to 1/10 of 1% of the population in each state in order to estimate the percentage of the population in that state earning over ,000 a year. The accuracy to be expected in california (population 35 million) is about the same as the accuracy to be expected in nevada (population 2 million). (ii) The accuracy to be expected in california is quite a bit higher than in. The accuracy to be expected in california is quite a bit lower than in. Explain. (i) is true, since if both samples are representative of their populations, then sheer sample size does not matter.
