2. The white wood material used for the roof of an ancient temple is imported from a certain country. The wooden roof must withstand as much as 100 centimeters of snow in the winter. Architects at a university conducted a study to estimate the mean bending strength of the white wood roof. A sample of 16 pieces of the imported wood were tested and yielded the statistics x = 72.1 and s = 11.8 on breaking strength (MPa). Estimate the true mean breaking strength of the white wood with a 90% confidence interval. Interpret the result. Find the 90% confidence interval for the true mean breaking strength of the white wood. (Round to two decimal places as needed.) Interpret this confidence interval. Choose the correct answer below. O A. The architects can be 90% confident that the mean breaking strength of the white wood is within this interval. O B. The architects can be 10% confident that the mean breaking strength of the white wood is within this interval. O C. The architects are confident that 90% of the white wood is described by this interval. O D. The architects can be 95% confident that the mean breaking strength of the white wood is outside this interval. O E. The architects can be 10% confident that the mean breaking strength of the white wood is 72.1
