The assembly line that produces an electronic component of a missile system has historically resulted in a 2% defectiverate. a r

andom sample of 800 components is drawn. what is the probability that the defective rate is greater than 4%? suppose that in the random sample the defective rate is 4%. what does that suggest about the defective rate on the assembly line

<span>Defective rate can be expected to keep an eye on a Poisson distribution. Mean is equal to 800(0.02) = 16, Variance is 16, and so standard deviation is 4.
X = 800(0.04) = 32, Using normal approximation of the Poisson distribution Z1 = (32-16)/4 = 4.
P(greater than 4%) = P(Z>4) = 1 – 0.999968 = 0.000032, which implies that having such a defective rate is extremely unlikely.</span>

<span>If the defective rate in the random sample is 4 percent then it is very likely that the assembly line produces more than 2% defective rate now.</span>

The cone in the figure below has a volume of 72π cubic centimeters and a height of 6
AleksAgata [21]

Answer:

6 cm

Step-by-step explanation:

The volume of a cone = (1/3) πr²h

72π = (1/3) π r² 6

72 = (1/3) r² 6

Divide both sides by 6

12 = (1/3) r²

Multiply both sides by 3

36 = r²

So r (radius) = 6 cm

Snezhnost [94]

Answer:

1:1.5

Step-by-step explanation:

We have that 150 meters in the reality and the new size in the drawing is 2/3, therefore

150mtrs(old) * 2/3 = 100mtrs(new), also 100 mtrs. in the drawing are 150mtrs. in the reality or 1 is to 1.5

1:1.5
