Select one:
a. 50
b. 30
c. 40
d. 20
Answer:
The correct option is a
Step-by-step explanation:
Generally standard deviation for is mathematically represented as
Where n is the sample size
So from the equation we see that
So this tell us that the more the sample size the lesser the standard deviation so the correct of to is A

If you're asking us to solve for Z...
z² + 11z = -21/4
4z² + 44z + 21 = 0
Enter... *drumroll* the quadratic equation!
(that's a plus or minus, sorry)
x = -0.5 or -10.5
Does this help? Is it too complicated? Do you have any questions?
The value of x that makes the equation true can be found by multiplying both sides of the equation by 7.
x = 70
