Modeling and Simulation (Geometric Distribution) Q1)At Colombia University, each student has a probability of 0.8 to pass the simulation exam. Denote by X the random variable that represents the number of times a student must take the simulation exam in order to pass it (assume independent outcomes for each trial, and that probability of success remains the same). i)What is the average number of times a student has to take the exam?

CLT for Proportions The proportion of taxpayers who file within 45 days of the tax season is 36.4%. 1. What is the proportion of taxpayers that file after 45 days? 2. If you randomly select 60 taxpayers, what is the probability that at least 40% file within 45 days? 3. If you randomly select 115 taxpayers, what is the probability that at most 35% file within 45 days? 4. If you randomly select 140 taxpayers, what is the probability that between 36% and 39% file within 45 days? 5. Describe this distribution (sample proportion) in statistical notation when n=90
Salinity in Quebec river is a combination of tides and rain. Rain that diluted the salt occurs about 10% of the time, while the non salty outgoing tides occurs twice per day. You take your dog for a walk down by the river at random during the weekend and notice that he'll drink from the river 30% of the time when the salt is sufficiently low. Question Given that the overall probability of rain remains 10 % what is the probability of rain during a non tide period?

At the close of the stock markets on a day in 2013, there were 5905 companies listed with a certain stock exchange. On this day, the probabilities of advancing, declining, and unchanged company stocks appears in the table for the two exchanges. Find the probability an advancing stock was listed on Exchange 1. Percentage of Probability of Probability of Companies Probability the Stock Stock Stocks Remain Exchange Exchange 1 Exchange 2 Declining 0.267 Listed Advancing Unchanged 0.041 54.8% 0.684 45.2% 0.657 0.297 0.046 ..... The probability that an advancing stock was listed on Exchange 1 is (Round to three decimal places as needed.)

Perform a statistical analysis / test of hypothesis Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table. Student Pair 1 2 3 4 5 6 7 8 9 10 Reading Score under Computer Method 85 80 95 87 78 82 57 69 73 99 Reading Score under phonics method 80 80 88 90 72 79 50 73 78 95 Test whether there is a significant difference between the computer method and the phonics method. If there is a significant difference, which particular method…

Game of chance: A player rolls a fair six-sided die. If outcome of a roll is an odd number, the player wins as many dollars as there are dots on the top face . Otherwise, the player looses 4 dollars. Let the random variable X be profit (amount won or lost) per game. Make a probability distribution table for the random variable: amount won or lost. Find the Expected value of the experiment Use Law of Large numbers to interpret the meaning of the Expected value If a person plays 100 times, how much he expects to win/loose?
