0.0180 Question 29-31 are related to the following On a freeway 8596 of vehicles violate the speed limit (it = 0.85). From the population of all vehicles on the freeway, you clock repeated random samples of size 480 vehicles 29 What fraction of sample proportions (p's) from samples of size 480 fall with 10.02 (2 percentage points) from the population proportion. 0.7802 0.7575 0.7354 0.7140 30 The middle interval that captures 95% of sample proportions is. 0.818 0.882 0.805 0.895 0.787 0.913 0.761 0.939 31 To build a middle interval around the population proportion it such that 95% of all sample proportions deviate from the population proportion by no more than 10.02 (2 percentage points), what is the minimum sample size to yield this interval? 1164 1225 1289 1357 32 The middle interval around the population proportion which captures 95% of sample proportions of ehicles that exceed the speed limit is 0.832 0.891 What was the sample size to build this interval 476 501 527 555 33 Among adult residents of a certain state 74% have more than 12 years of schooling We want to build a middle interval (p. p.) centered at n = 0.74 such that it captures 98% of all sample proportions within 20.025 (2.5 percentage points) from the population proportion. What is the required sample size? 1429 1504 1583 1666 34 Rick O'shea is one of the two candidates running for the governor of a Midwestern state. Suppose Rick O'shea has 47 percent of the votes among all the voters in the state. Just before the election a local TV news polls a random sample of 450 voters. What is the probability that the poll will predict Rick O'Shea winning the election? 0.1982 0.1416 0.1011 0.0722 35 What should the sample size be in order to reduce the probability of wrongly predicting Rick O'shea's victory to 0.035? 804 838 873 909
