Chapter 8 assessment 1. suppose a random sample of 100 farm-raised salmon showed an average concentration of mirex (a toxic insecticide) of 0.0761 ppm, with a sample standard deviation of 0.0239 ppm. a. (5 points) use this information to compute a 95% confidence interval for the population mean concentration of mirex in farm-raised salmon. clearly show that you checked to make sure the data meet all necessary conditions for inference. b. (5 points) interpret the meaning of the confidence interval you found in part a in the context of this application. 2. suppose that a simple random sample of 250 u.s. adults showed that 145 of them believe the death penalty is applied fairly. a. (5 points) use this information to compute a 99% confidence interval for the population proportion of u.s. adults who believe the death penalty is applied fairly. clearly show that you checked to make sure the data meet all necessary conditions for inference. b. (5 points) interpret the meaning of the confidence interval you found in part a in the context of this application.
