A confidential survey aims to estimate the percentage of drive
Question

Question asked by Filo student

A confidential survey aims to estimate the percentage of drivers who text while driving. To allay fear that confidentiality might be breached, the following method is employed. A subject is asked to pick a random number between 1 and 100 (without revealing it). If it is between 21 and 55, they answer the question, "Do you text and drive regularly?" Otherwise, they answer the question, "Is the month of your birthday an even number?" 37.5% of all responses are "Yes". What is the percentage of drivers who answer the texting question with "Yes"?

Texts: Assume that the population has a normal distribution. Round the confidence interval limits to the same number of decimal places as the sample standard deviation. The mean replacement time for a random sample of 20 washing machines is 10.9 years and the standard deviation is 2.7 years.
  1. Identify the values of n and s.
  2. Find the critical value.
  3. Find the XR critical value.
  4. Construct a 99% confidence interval for the standard deviation, σ, of the replacement times of all washing machines of this type.

CRB of Geometric distribution (20 pts): Let T be a discrete random variable taking values following a geometric distribution. p(X = T; θ) = θ(1 - θ)^(T-1)
  1. (10 pts) Derive the log-likelihood function, L(θ; X), for a single sample.
  2. (10 pts) Given samples, write down the log-likelihood of the joint density f(X; θ), assuming independence.
  3. (5 pts) Calculate the Fisher Information for i.i.d. samples.
  4. (5 pts) Calculate the Cramer-Rao Lower Bound (CRB) for i.i.d. samples.

A certain party takes place in two rooms: the living room (A) and the kitchen (B). After every 15 minutes, each person at the party decides whether to move to a different room or leave the party (C). If any given party-goer is in the living room, then she will stay in the living room with a 95 percent probability or move to the kitchen with a 5 percent probability. If a party-goer is in the kitchen, then she will stay in the kitchen with a 50 percent probability, move to the living room with a 40 percent probability, or leave the party with a 10 percent probability. If a party-goer has left the party, she may return to the living room with a certain probability or never return (that is, stay in state C) with a probability of 99 percent. Find the stochastic matrix governing the movements of the party-goers. Find the steady state vector. Explain what the steady state vector means for the party-goers. If 80 percent of the people are in the living room and 20 percent of the people are in the kitchen at a given time, where are the people half an hour later? I am asking for the percentages of each; what percentage of people are at A, B, C?
