Step-by-step explanation:
Answer:
5 ; 0.728 ; 0.00002
Step-by-step explanation:
According to the Central limit theorem, for a normal distribution, the population mean equals the sample mean., Hence the population mean, μ = sample mean = 5
The standard deviation of sampling distribution :
Standard deviation / sqrt(n)
σ / sqrt(n)
σ = 3 ; n = 17
3 / sqrt(17)
3 / 4.1231056
= 0.7276
= 0.728
3.)
P(x < 2) :
Using :
Z = (x - mean) ÷ s/sqrt(n)
P(x < 2) = (2 - 5) ÷ 3/sqrt(17)
P(x < 2) = -3 / 0.7276068
P(x < 2) = - 4.1231060
Z < - 4.123 = 0.00002 (Z probability calculator).
Answer:
-6/7
Step-by-step explanation:
Slope is negative, around -1
2.75+.003+.158=0
We simplify the equation to the form, which is simple to understand
2.75+.003+.158=0
We move all terms containing to the left and all other terms to the right.
0=0-2.75-0.003-0.158
We simplify left and right side of the equation.
0=-2.911
0=-2.911
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
