Atype of thread is being studied for its tensile strength properties. fifty pieces were tested under similar conditions, and the results showed an average tensile strength of 78.3 kilograms and a standard deviation of 5.6 kilograms. assuming a normal distribution of tensile strengths, give a lower 95% prediction limit on a single observed tensile strength value. in addition, give a lower 95% tolerance limit that is exceeded by 99% of the tensile strength values.
