      = one-sigma rms acceleration response of PCB, g’s; P = power spectral density input at / Hz. Combining Eqs. 1, 2, 3 and 5 yields the desired PCB resonant frequency for achieving about 20 million stress reversals as a fatigue life in a random vibration environment. Equation 6 takes into account 3-sigma acceleration peaks. (6) Mechanical shock

      The cost of the product or cost of testing is very expensive. The sample is from a chemical process such as the liquid in a vat. The process has demonstrated a low variance and warrants reduced testing and the associated cost savings. The 3 sigma limits are process capability limits so the process is generally monitored to 2 sigma limits.

      An oyster bar buys fresh oysters for $3 per pound and sells them for $10 per pound. Unsold oyster at the end of the day is sold to a grocery store for $1.20 per pound. Determine the pounds of oysters that must be ordered each day if the daily demand follows normal distribution with mean of 150 pounds and standard deviation of 12 pounds.
