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 overbar equals 75.7 and s equals 10.9 on breaking strength (MPa). Estimate the true mean breaking strength of the white wood with a 95 % confidence interval. Interpret the result.
