- Can the idea of joint random variables apply to more than two variables or is it just strictly like an X and a Y variable? Explain in 1-2 sentences. Thanks in advance!About 70% of babies born with a certain ailment recover fully. A hospital is caring for seven babies born with this ailment. The random variable represents the number of babies that recover fully. Decide whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. Is the experiment a binomial experiment? Yes No What is a success in this experiment? Baby recovers Baby doesn't recover This is not a binom experiment. Specify the value of n. Select the correct choice below and fill in any answer boxes in your choice. A. n= OB. This is not a binomial experiment. Specify the value of p.

- Roll a die until you get 7 twos and count the number of rolls required. Does this process describe a binomial random variable? If it is binomial, give values for n and p. If it is not binomial, enter NA in both entry fields. n = p =About 30% of babies born with a certain ailment recover fully. A hospital is caring for seven babies born with this ailment. The random variable represents the number of babies that recover fully. Decide whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. Is the experiment a binomial experiment? Yes No What is a success in this experiment? a.Baby recovers b.This is not a binomial experiment. c.Baby doesn't recover Specify the value of n or not A. n=? B. This is not a binomial experiment. -Specify the value of p or is This not a binomial experiment. -Specify the value of q. A. q=? B. This is not a binomial experiment. List the possible values of the random variable x.A QR code photographed in poor lighting, so that it can be difficult to distinguish black and white pixels. The gray color (X) in each pixel is therefore coded on a scale from 0 (white) to 100 (black). The true pixel value (without shadow) the code is Y = 0 for white, and Y = 1 for black. We treat X and Y as random variables. For the highlighted pixel in the figure is the gray color X = 20 and the true pixel value is white, i.e. Y = 0. We assume that QR codes are designed so that, on average, there are as many white as black pixels, which means that pY (0) = pY (1) = 1/2. In this situation, X is continuously distributed (0 ≤ X ≤ 100) and Y is discretely distributed, but we can still think about the simultaneous distribution of X and Y. We start by defining the conditional density of X, given the value of Y : fX|Y(x|0) = "Pixel is really white" fX|Y(x|1) =" Pixel is really balck " Use Bayes formula as given in the picture and find the probability for x = 20 like in the picture.
- Please answer q's a, b, and c For this case, a=3, b=9, and label the random variable A. Student ID number: 300546514Suppose you flip a coin times. Let the number of heads that turn up. The random variable is a binomial random variable because the random procedure in question (i.e., flipping 10 coins) satisfies four specific requirements. List the four requirements and explain briefly why each one is satisfied.Safety switch An industrial machine requires an emer-gency shutoff switch that must be designed so that it can be easily operated with either hand. Design an experi-ment to find out whether workers will be able to deacti-vate the machine as quickly with their left hands as with their right hands. Be sure to explain the role of random-ization in your design.
- 2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:You currently work for the DARPA, the Defense Advanced Research Projects Agency. You've received reports of some strange things occurring in the small town of Hawkins, Indiana. Let U be a random variable equal to 1 if the citizen has been to the Upside Down and 0 otherwise. Let S be a random variable equal to 1 if a citizen reports being in the presence of a group of misfit kids who claim to be "saving the town" and 0 otherwise The table below shows the joint probability density function for the galactic population Share of Population 0.15 0.32 0.50 0.03 U 0 0 1 1 S 1 0 1 0 Round to 2 decimal places where necessary, unless otherwise stated. Leave your answer in decimals, rather than convert to percentages. A. Evaluate Fu,s (1,0): B. Calculate the share of people who have been to the Upside Down in the population. That is, E(U): C. Calculate the probability of having gone to the Upside Down conditional on meeting this band of misfit kids?. That is, Fus (11):1. A bank operates a drive-up and walk-up window. Let X = the proportion of the time the drive-up facility is in use and let Y = the proportion of the time the walk-up window is in use. Suppose the operations manager uses the following distribution as the joint pdf based on his historical data: f(x, y) = 5 - 1/2(x + y²) if 0 (x + y²) if 0 ≤ x ≤ 1 and 0 ≤ y ≤1 otherwise (a) Find the marginal pdf for X, fx(x). (b) Find the marginal pdf for Y, fy(y).
