The weights at birth of five randomly chosen baby giraffes were 111, 115, 120, 103, and 106 pounds. Assume the distribution of weights is normally distributed. Find a 95% confidence interval for the mean weight of all baby giraffes. Use technology for your calculations. Give the confidence interval in the form "estimate ± margin of error." Round to the nearest tenth of a pound.
◦ There is not enough information given to calculate the confidence interval.
◦ 111.0 ± 8.5 pounds
◦ 111.5 ± 9.0 pounds
◦ 110.0 ± 8.5 pounds
