Lyme disease is spread in the northeastern United States by infected ticks. The ticks are infected mainly by feeding on mice, so more mice result in more infected ticks. The mouse population in turn rises and falls with the abundance of acorns, their favored food. Experimenters studied two similar forest areas in a year when the acorn crop failed. They added hundreds of thousands of acorns to one area to imitate an abundant acorn crop, while leaving the other area untouched. The next spring, 55 of the 77 mice trapped in the first area were in breeding condition, versus 10 of the 18 mice trapped in the second area. Give a 99% confidence interval for the difference between the proportion of mice ready to breed in good acorn years and bad acorn years. Follow the Inference Toolbox. lower bound upper bound
