Which one of the following statements is false? Group of answer choices A correlation of –0.70 is just as strong as a correlation of +0.70. A sampling distribution is a collection of sample statistics. Chance behavior is predictable in the long run but has an unpredictable pattern in the short run. The size of the sample proportion has no impact on the margin of error. As the sample size gets larger, the standard deviation of the sampling distribution will get smaller.
