However, it is not known whether this method is equivalent to the traditional method of static weighing. Find a 95% confidence interval of the weight differences. Interpret this interval in context. Click the icon to view the table of weights. The confidence interval is (].). Round to one decimal place as needed.) Interpret this interval. Choose the correct answer below. O A. The true mean difference between static weight and weight-in-motion for all trucks falls within this interval 95% of the time. O B. About 95% of all samples of trucks will have a mean difference between static weight and weight-in-motion that falls within this interval. O C. There is a 95% chance that this interval captures the mean difference between static weight and weight-in-motion of the population of trucks. O D. One can have 95% confidence that this interval captures the true mean difference between the static weight and weight-in-motion for all trucks.

(Round to two decimal places as needed.) Interpret the confidence interval. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) A. Based on these samples, with 95% confidence, children's cereals average between the lower boundary of and upper boundary of more grams of sugar content than adult's cereals. O B. Based on these samples, with 95% confidence, adult's cereals average between the lower boundary of | |and upper boundary of more grams of sugar content than children's cereals.
