What is the confidence level associated with this statement? Answer: (1 – a) = b) Give a 95% confidence interval to estimate the average bond strength of these energetic materials. Answer: = -n c) How much additional data must be sampled if one wants to estimate the adhesion strength to the nearest 25 with a confidence level of 99%. Answer:
