Assume that X has a normal distribution, and find the indicated probability. The mean is u=15.2 and the population standard deviation is 0.9. Find the probability that X is greater than 15.2

0.5

Step-by-step explanation:

First, find the z score.

z = (x − μ) / σ

z = (15.2 − 15.2) / 0.9

z = 0

Use a calculator or z-score table to find the probability.

P(X > 15.2)

= P(Z > 0)

= 0.5

the probability that X is greater than 15.2 is 0.5

Step-by-step explanation:

Assume that X has a normal distribution, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

µ = mean

σ = standard deviation

From the information given,

µ = 15.2

σ = 0.9

We want to find the probability that X is greater than 15.2. It is expressed as

P(x > 15.2) = 1 - P(x ≤ 15.2)

For x = 15.2

z = (15.2 - 15.2)/0.9 = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:
