Suppose you are conducting an experiment where you flip a coin four times and count the number of heads flips. For such an experiment, you can either get 0/4, 1/4, 2/4, 3/4, or 4/4 heads.

a. Explain why there are five bars in the sampling distribution for this experiment.

b. Draw a sampling distribution for this problem.

c. Use the equation √p * (1-p)/n  to determine the mean and standard deviation of the sampling distribution of sample proportions with samples of size 4.

java beginner level NO ARRAYS in program Flip a coin (Assignment) How many times in a row can you flip a coin and gets heads? Use the random number generator to simulate the flipping of the coin. 0 means heads, 1 means tails. Start a loop, flip it, if heads, count it and keep flipping. If tails, stop the loop. Display the number of times in a row that heads came up. Once this is working, wrap a while loop...

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")...
