X is a Gaussian random variable with variance 9. It is known that the mean of X is positive. It is also known that the probability P[X^2 > a] (using the standard Q-function notation) is given by P[X^2 > a] = Q(5) + Q(3). (a) [13 pts] Find the values of a and the mean of X (b) [12 pts] Find the probability P[X^4 -6X^2 > 27]

A worn machine is known to produce 10% defective components. If the random variable X is the number of defective components produced in a run pf 3 components, find the probabilities that X takes the values 0 to 3. Suppose now that a similar machine which is known to produce 1% defective components is used for a production run of 40 components.We wish to calculate the probability that two defective items are produced. Essentially we are assuming thatX~B(40,0.01) and we...

Consider a finite population of size N in which the mean of the variable of interest Y is u. Suppose a sample of size n is taken from this population using simple random sampling with replacement. Suppose that the sample mean Y is used to estimate u. (a) [3 marks] Calculate the probability of sample and probability of inclusion for this sam- pling protocol. (b) (4 marks] Show that Y is unbiased for u. (c) [4 marks] Calculate Var(Y). Make...

Suppose that Xi’s are coming from a normal population with a mean μ =10 and known variance σ=2. Generate 100 samples of n=50 observations coming from the population of interest. Please, construct the 90% confidence interval for each sample and report the number of confidence intervals that include the mean μ value. Compare this number with the expected number of confidence intervals that include the mean μ value. please help me. i colud not solve it

An enterprise that holds a variable interest in a variable interest entity (VIE) is required to consolidate the assets, liabilities, revenues, expenses, and noncontrolling interest of that entity if: The VIE has issued no voting stock. The variable interest held by the enterprise involves a lease. The enterprise has a controlling financial interest in the VIE. Other equity interests in the VIE have the obligation to absorb the expected losses of the VIE.
