Answer:
By the Empirical Rule,
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 symbol of a standard deviation is . So
When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?
By the Empirical Rule,
First multiply (4x5)
Then find 2 cubed = 2x2x2= 8
Then divide 20 by 2= 20/2=10
Then 10-8= 2
Then find 2 cubed = 2x2x2= 8
Then divide 20 by 2= 20/2=10
Then 10-8= 2
