Question 2
1. A survey is to be conducted to estimate the proportion of individuals in a city who favor a particular political candidate. What is the minimum sample size required to ensure that the margin of error in the estimate is at most 3% when the level of confidence is 90%? 2. A sample of 12 radon detectors of a certain type was selected, and each was exposed to 100 pCi/L of radon. The resulting readings were as follows: 104.3, 89.6, 89.9, 95.6, 95.2, 90.0, 98.8, 103.7, 98.3, 106.4, 102.0, 91.1 a) Does this data suggest that the population mean reading under these conditions differs from 100? State all assumptions and test the appropriate hypotheses using a = 0.05. b) Construct a 95% confidence interval for the population mean reading. 3. From telephone interviews with 980 teenagers, it was found that 765 of those teenagers supported legalization of marijuana.
