Quadrant 3 should be your answer
Answer:
The probability that a light bulb picked at random will last between 1400 and 1500
P(14 00≤X≤1500) = 0.032
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that mean of the Population = 1000
Given that the standard deviation of the Population = 250 hours
Let 'X' be the random variable in a normal distribution
Let X = 1400
Let X = 1500
The probability that a light bulb picked at random will last between 1400 and 1500
P(x₁≤ X ≤x₂) = P(Z₁≤ Z ≤z₂)
= A( Z₂ ) -A(Z₁)
P(1400≤X≤1500) = P(1.6≤ Z ≤2)
= A(2 ) -A(1.6)
= 0.4772-0.4452
= 0.032
<u><em>Final answer:</em></u>-
The probability that a light bulb picked at random will last between 1400 and 1500
P(14 00≤X≤1500) = 0.032
