Which of the following statements is not true if the precision interval for a sampling risk of 10 percent ranges from 60 to 70?
A) A 10 percent probability exists that the true population value is less than 60 or more than 70.
B) A 90 percent probability exists that the true population value is less than 60 or more than 70.
C) The reliability is 90 percent.
D) The precision is 5.

A precision interval for a sampling risk of 10 percent ranging from 60 to 70 means that there is a 90 percent probability that the true population value falls within this range. Therefore, statement B is not true, as it suggests the opposite. Statement A is true because there is a 10 percent probability that the true population value is outside of the range. Statement C is true because the reliability, or confidence level, is 90 percent. Statement D is not relevant to the given information, as precision is typically measured as a margin of error or range around a point estimate, not as a percentage.
