A researcher wishes to estimate the mean length of North American adult bullfrogs. To do so, a random sample of 69 frogs is selected. Their mean length is 130.1 cm. We will assume that the population lengths are normally distributed with population standard deviation 24.2 cm. Construct the 99% confidence interval for the mean population length. Show your relevant steps below. Intermediate Calculations: z value = (Enter the number.) (cm) (cm) Standard Error = Maximum Error of Estimate : Final Answer: The 99% Confidence Interval of the true mean length of North American bullfrogs is (Lower Limit, Upper Limit) cm, cm)
