6 - It is desired to compare the yields of two different types of wheat seeds. It was observed that an average of 525 kg of product per hectare and an average of 450 kg of product per hectare was obtained in 200 randomly selected fields, where X' type seeds were sown, and an average of 525 kg of product per hectare in 100 randomly selected fields. Since the error of the difference between the means is 13.93, indicate the confidence limits of the difference between the yields of both wheat seeds with 99% probability.
