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: t = 11/2
Step-by-step explanation:
Answer:
q > 3
Step-by-step explanation:
12q>36
Divide each side by 12
12q/12>36/12
q > 3
The residual is the difference between the predicted value and the real value. Using the equation, we find for the value of y using the given value of x.
y = -2.5 + 5x
y = -2.5 + 5(3)
y = 12.5
The difference between this value and the given value of y is 12.5 - 6 = 6.5
Thus, the residual is equal to 6.5.
