1. Multiple choice. Circle all the correct answers a) You flip a coin 100,000 times and record the outcome in a Xi 1 if the toss is "Heads" and 0 if its "Tails. The Law of Large Numbers says that: i. ii. It is impossible for the first n flips to all be "Heads" if n is large. With high probability, the share of coin flips that are "Heads" will approximate 50%. The sample mean of X is always 0.5...

1a) Suppose you flip a weighted coin 19 times with probability of heads 0.55. Let X equal the number of heads. What is the mean number of heads (to two decimal places)? 1b) Suppose we have weighted coin with probability of heads being 0.30. What is the probability of getting four heads in five flips, to 2 decimal places? 2) Suppose a particular stock follows the "random walk" model where on any given day there is a 0.02 chance that...

Styles First we will learn how to evaluate binomial distribution with the help of Excel. Let's flip a coin n times and count how many tails we are going to get. If n=0, then no coin is tossed and the only option is 0 tails. Therefore P(0)=1, the mean is 0 and the standard deviation is 0. We are going to do a simple table for n=0. First we will define columns. Click on cell A1 and type X for...

To determine whether the pipe welds in a nuclear power plant meet specifications a random sample of welds is selected, and tests conducted on each. Weld strength is measured as the force required to break the weld.
