Weights of rats have a mean of 117g and a standard deviation of 11g. Assume weights are normally distributed. An experiment needs rats that weigh in the lowest 20% of the population. What is the maximum weight a rat can be for this experiment?

A sample of 10 adult elephants had an average weight of 11,446 pounds. The standard deviation for the sample was 24 pounds. Find the 90% confidence interval of the population mean for the weights of adult elephants. Assume the variable is normally distributed. Round intermediate answers to at least three decimal places. Round your final answers to the nearest whole number.
