Assume the random variable x is normally distributed with mean mu equals 50μ=50 and standard deviation sigma equals 7σ=7. compute the probability. be sure to draw a normal curve with the area corresponding to the probability shaded. upper p left parenthesis upper x greater than 34 right parenthesisp(x> 34)

0.9890

Step-by-step explanation:

Given : Mean :

Standard deviation :

We assume the random variable X is normally distributed

The formula to calculate the z-score :-

For x=34.

The p-value =

Hence,

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
