Conducting a Simulation For example, say we want to simulate the probability of getting “heads” exactly 4 times in 10 flips of a fair coin. One way to generate a flip of the coin is to create a vector in R with all of the possible outcomes and then randomly select one of those outcomes. The sample function takes a vector of elements (in this case heads or tails) and chooses a random sample of size elements. coin <- c("heads","tails")...

1. Let n be an odd positive integer. Consider a list of n consecutive integers. Show that the average is the middle number (that is the number in the middle of the list when they are arranged in an increasing order). What is the average when n is an even positive integer instead? 2. Let x1,x2,...,xn be a list of numbers, and let ¯ x be the average of the list.Which of the following statements must be true? There might...

1 A fair coin is flipped 15 times. Each flip is independent. What is the probability of getting more than ten heads? Let X = the number of heads in 15 flips of the fair coin. X takes on the values 0, 1, 2, 3, ..., 15. Since the coin is fair, p = 0.5 and q = 0.5. The number of trials is n = 15. State the probability question mathematically. 2 Approximately 70% of statistics students do their...

Write a complete Java program to solve the following problem. Read two positive integers from the user and print all the multiple of five in between them. You can assume the second number is bigger than the first. For example if the first number is 1 and the second number is 10, then your program should output 5 10 Note: There is a white space in between the numbers. Java programming please answer ASAP before 2:30

1. a.) Suppose you draw 8 cards from a standard deck of 52 cards, one after the other, without replacement. Find the probability that the last card is a club given that the first 7 cards are clubs. b.) An urn contains 6 green, 10 blue, and 17 red balls. You take 3 balls out of the urn, one after the other, without replacement. Find the probability that the third ball is green given that the first two balls were...

In a lottery of 5 different numbers are chosen from the first 90 positive integers. a) How many possible outcomes are there? (An outcome is an unordered sample of five numbers) b)How many outcomes are there with the number 1 appearing among the five chosen numbers? c) How many outcomes are there with two numbers below 50 and three numbers above 60? d)How many outcomes are there with the property that the last digits of all five numbers are different?...

16) Players A and B take turns drawing from an urn of 10 balls. One ball contains a prize, and the rest contain nothing. If player A draws first, and all draws are without replacement, find the probability of A winning. Is it more or less than the probability of B winning? 17) 3 fair coins are fipped behind a screen so that you cannot see the result. What is the probability that there is at least 1 tail? A...

Fair Coin? In a series of 100 tosses of a token, the proportion of heads was found to be 0.39. However, the margin of error for the estimate on the proportion of heads in all tosses was too big. Suppose you want an estimate that is in error by no more than 0.04 at the 90% confidence level. (a) What is the minimum number of tosses required to obtain this type of accuracy? Use the prior sample proportion in your...
