Exercise 4 (Continuous Probability) For this exercise, consider a random variable X which is normally distributed...
Assume the random variable x is normally distributed with mean μ=85 and standard deviation σ=4. Find the indicated probability.P(x<81)
Assume the random variable x is normally distributed with mean μ=88 and standard deviation σ=4. Find the indicated probability. P(78<x<82)
The random variable X is normally distributed. Also, it is known that P(X > 150) = 0.10. [You may find it useful to reference the z table.] a. Find the population mean μ if the population standard deviation σ = 15. (Round "z" value to 3 decimal places and final answer to 2 decimal places.) b. Find the population mean μ if the population standard deviation σ = 25. (Round "z" value to 3 decimal places and final answer to...

Find the probability that x assumes a value a. between 28 and 34 b. between 20 and 35 6.34 Let x be a continuous random variable that has a normal distribution with a mean of 30 and a stan- dard deviation of 2. Find the probability that x assumes a value a. between 29 and 35 b....
Let X be a continuous random variable that is normally distributed with a mean of 65 and a standard deviation of 15. Find the probability that X assumes a value less than 46. Round your answer to four decimal places. P=???
