Measurements of the flexible strength of carbon fiber are carried out during the design of a leg prosthesis. After 15 measurements, the mean is calculated as 1725 MPa with a standard deviation of 375 MPa. Previous data on the same material shows a mean of 1740 MPa with a standard deviation of 250 MPa. Use this information to estimate mean and standard deviation of the posterior distribution of the mean. Note: round your answers to only 2 decimals. The mean value of the posterior is type your answer... MPa and the standard deviation is type your answer... MPa.
