Domestic cats kill many more wild birds in the United States than scientists thought,” states a recent article.1 Researchers used a sample of n = 140 households in the US with cats to estimate that 35% of household cats in the US hunt outdoors. a. Find a 99% confidence interval for the proportion of household cats in the US that hunt outdoors using this sample information. Show work/calculations used to find SE, ME and confidence interval to full receive credit. Round your answers to three decimal places. b. Interpret your 95% confidence interval in a complete sentence. Use correct units and context. c. Is it plausible that the proportion of household cats in the US hunting outdoors is 0.45? Briefly explain why or why not?
