    Chapter 1 1.2 Descriptive techniques summarize data. Inferential techniques draw inferences about a population based on sample data. 1.3 a The population is the 25,000 registered voters. b The sample is the 200 registered voters. c The 48% figure is the s tatistic 1.4 a The population is the complete production run. b The sample is comprised of the 1,000 chips. c The parameter is the proportion of defective chips in the production run. d The statistic is the proportion of defective chips in the sample. e The 10% figure refers to the parameter. f The 7.5% figure refers to the s tatistic . g We can estimate the population proportion is 7.5%. Statistical inference methods will allow us to determine whether we have enough statistical evidence to reject the claim. as the sample proportion. 1.5 Draw a random sample from the population of graduates who have majored in your subject and a random sample of graduates of other majors and record their highest salary offers. 1.6 a Flip the coin (say 100 times ) and record the number of heads (assuming that you are interested in the number of heads) . b The population is composed of the theoretical result of flipping the coin an infinite number of times and recording either “heads” or “tails”. c The sample is comprised of the “heads” and “tails” in the sample. d The parameter is the proportion of heads (again assuming that your interest is the number of heads rather than tails) in the population. e The statistic is the proportion of heads (or tails depending on the choice made in part d). f The sample statistic can be used to judge whether the coin is actually fair. 1.7 a We would conclude that the coin is not fair. b We may conclude that there is some evidence that the coin is not fair. 1.8 a The population is made up of the propane mileage of all the cars in the fleet. b The parameter is the mean propane mileage of all the cars in the fleet. c The sample is composed of the propane mileage of the 50 cars.
