Shania loves squirrels, but she has no idea what the mean of her squirrels weight is. She takes a random sample of n=214 squirrels and obtains a 95% confidence interval for µ, the true mean weight of all of the squirrel weights in her yard – 0.8 to 1.4 lbs. Which of these is the correct interpretation of her confidence interval? A. Shania can be 95% confident that the true mean weight of the squirrels in her yard is between...
