Suppose you know the values of : Mean = E ( X ) and Variance = V(X) of a variable X in a given population. Indicate how you will construct T1 and T2 such that P( T1 < Xf < T2 ) = 0.9 (approximately), where X¬f is the value of X you will observe on the individual you will draw randomly from the population. Assume that you know X0 ≠ Xf , which is a realized value of X. [Do not assume that X is normal.]

For a continuous random variable X , you are given that the mean is E(X)= m and the variance is var(x)= v. Let m=(R+L)/2 Given L = 6, R = 113 and V = 563, use Chebyshev's inequality to compute a lower bound for the following probability P(L<X<R) Lower bound means that you need to find a value  such thatP(L<X<R)>p using Chebyshev's inequality.

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 415415 gram setting. Based on a 2424 bag sample where the mean is 409409 grams and the variance is 784784, is there sufficient evidence at the 0.10.1 level that the bags are underfilled? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. A manufacturer of banana chips would like to know whether its bag...

Problem 7 Suppose you have a random variable X that represents the lifetime of a certain brand of light bulbs. Assume that the lifetime of light bulbs are approximately normally distributed with mean 1400 and standard deviation 200 (in other words X ~ N(1400, 2002)). Answer the following using the standard normal distribution table: Approximate the probability of a light bulb lasting less than 1250 hours. Approximate the probability that a light bulb lasts between 1360 to 1460 hours. Approximate...

Suppose that f(x)=x−3x^1/3 (A) Find all critical values of f. If there are no critical values, enter -1000. If there are more than one, enter them separated by commas. Critical value(s) = (B) Use interval notation to indicate where f(x) is increasing. Note: When using interval notation in WeBWorK, you use INF for ∞∞, -INF for −∞−∞, and U for the union symbol. If there are no values that satisfy the required condition, then enter "{}" without the quotation marks....
