it is not a parabola-not exponent, so no U shapes, and has a negative slope, which means it is heading downards
Answer:
0.0082
Step-by-step explanation:
Data provided in the question:
Mean = 10
Variance = 25
Standard deviation =
n=36
Given
By using z-table we get,
= 0.0082.
Answer:
Explanation:
Flip Equation
ntw = v
Divide both sides by 'nt'
ntw / nt = v / nt
Answer:
The answer is explained below
Step-by-step explanation:
We have the following formulas:
from binomial distibution: P (X = x) = (nCx) * (p) x * (1-p) n-x
from normal distribution: P (X <= x) = (x-np) / sqrT (np (1-p))
Now, n = 25 and p (0.5, 0.6, 0.8), we replace in the formulas and we are left with the following table:
P P(15<=X<=20) P(14.5<=X<=20.5)
0.5 0.2117 is less than 0.2112
0.6 0.5763 is less than 0.5685
0.8 0.5738 is greater than 0.5957
