When an unknown data sample was analyzed using a given analytical technique, it was found to yield an analytical signal of 32.8 0.32 (n = 1000 measurements). The company decided that the time per measurement was the limit of throughput for the system and wanted to reduce the total analysis time by reducing the number of individual measurements per sample. a. Calculate the S/N ratio for the sample when 1000 independent measurements were made. b. The company decided that for this given analysis, a S/N ratio of 10 was an acceptable value. How many measurements are required to obtain a S/N ratio of 10 for this sample?
