Question: Suppose a variable X is normally distributed with a standard deviation of 10. Given that 0.0985 of the values of X are greater than 70,

Suppose a variable X is normally distributed with a standard deviation of 10. Given that 0.0985 of the values of X are greater than 70, what is the mean value of X?

Given the normally distributed random variable X with mean 100 and standard deviation 15, find the numerical value of x such that:

a. P(X x) = 0.0094

b. P(X x) = 0.1093

c. P(100 X x) = 0.4778

Given the normally distributed random variable X with standard deviation equal to 10 and

P(X 40) = 0.0080, find the mean.

X is a normally distributed random variable X with mean of 28 and standard deviation of 3.7. If P(x1 < X < x2) = 0.65, what is the value of x1? Do not round off.
