Answer:
P(X > 112) = 0.21186.
Step-by-step explanation:
We are given that the random variable X is normally distributed, with mean
= 100 and standard deviation
= 15.
Let X = <u><em>a random variable</em></u>
The z-score probability distribution for the normal distribution is given by;
Z =
~ N(0,1)
where,
= population mean = 100
= standard deviaton = 15
Now, the probability that the random variable X is greater than 112 is given by = P(X > 112)
P(X > 112) = P(
>
) = P(Z > 0.80) = 1- P(Z
0.80)
= 1 - 0.78814 = <u>0.21186</u>
The above probability is calculated by looking at the value of x = 0.80 in the z table which has an area of 0.78814.
Answer:
40 or 50%. Let me write this down and solve it, hold on a second.
Answer:
i
Step-by-step explanation:
is the same thing as i, which is an imaginary number.
Since you can't take the square root of negative numbers, we use i to do it.
