Changes of 95% confidence interval with number of measured sources at three different measured strength deviations. The measured strength percent deviations are 1%, 5%, and 10%, respectively.
The relationship between measured strength deviation and number of measured sources required to achieve a 95% confidence interval of 3% for the percent difference between the expected and measured mean strength.
Impact of using in place of on . and the number of measured sources were assumed to be 5% and 14, respectively.
Changes of the 95% strength confidence interval with number of assayed sources when the manufacturer’s value is used instead of the assayed value. The percent difference between the manufacturer’s value and the assayed value were assumed to be and 3%, respectively. It was also assumed that the percent deviation of the assayed value was 5%. Presented also were the results with the percent deviation of the assayed value as 3% and .
95% confidence interval for the percent difference between the expected and measured mean source strength at different measured strength deviations and numbers of sources. The confidence intervals are in percentage.
