I think that the answer is 50 because 100 divided by 2 equals 50
Step-by-step explanation:
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, 
Answer:
4√2 or 5.66 to the nearest hundredth.
Step-by-step explanation:
Applying the Pythagoras Theorem:_
c^2 = a^2 + b^2
c^2 = 4^2 + 4^2
c^2 = 32
c = √32
c = 4√2
