Answer:
32%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
The sampling distribution of the sample means tend to be normally distributed.
What chance, in percent (0-100) does the next measurement have of being outside 1 standard deviation from the mean?
68% of the measures are within 1 standard deviation of the mean.
100 - 68 = 32% are outside of 1 standard deviation from the mean.
So the chance is 32%.
