A biologist is attempting to determine the mean weight of African elephants. She conducts a sample of 60 elephants, and finds a sample mean of 8311 lbs., with a standard deviation of 127 lbs. Assume that the distribution of weights of African elephants is nearly normal. Define your variable: O Let u be the mean weight of all African elephants, in lbs.. o Let u be the mean weight of the sampled African elephants, in lbs.. Let p be the proportion of elephants that weigh . O Let p be the proprotion of elephants in the sample. Create and interpret a 95% Confidence Interval. Round your answers to one decimal place. and Select an answer lbs. What is the margin of error? Round your answer to one decimal place. lbs. Another biologist believes that the mean weight of elephants is 8346. What do you think of this claim? O The claim is above the sample mean, so there is no way it can be true. The claim is inside the interval. It is reasonable. The claim is inside the interval. It must be true. O That claim is not in our interval. We do not believe it.
