Solution: C) 7.815
Hint: From Chi-square table with (k-r-1)=(6-2-1) = 3 d.f the critical value = 7.8147
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, 0).
Step-by-step explanation:
y = 8x - 32
There are many solutions that we can choose from, since any set of coordinates that fit in the equation counts as a solution.
We can have (0, -32), (1, -24), (2, -16), (3, -8), (4, 0), and many more.
Hope this helps!
It would be zero bc, 9x-7=-7 you do KCF Change the sign to addition so -7+7=0 now you divide 0 divided by 9=0. Hope this helps
