The adhesion resistance of 12 energetic materials (explosives, fuels and pyrotechnic compositions) was measured and the following values were obtained: 328 112 213 186 125 161 285 237 347 165 287 110 Answer: Mean: Standard Deviation: a) From these results, a technician states that the bond strength is between 172.5012 and 253.4988. 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:
