Sampling Distribution. We will be using some of your knowledge of statistics this semester, so you may need to use the resources you were provided in other class(es) and review a few concepts. First, review the meaning of the term "sampling distribution," as defined in your statistics course(s).

After looking it up in your statistics sources, read the following:

Now work on the following problem:

I have a random variable that represents the flip of a fair coin. If the outcome of the flip is Heads, the random variable takes on the value 1, and if it is Tails, it takes on the value 0. I am taking samples of size n=4, so a sample might look like {0, 1, 0, 0}. For this particular sample, the sample min is 0, the sample mean is 1/4, and the sample max is 1. Give the sampling distributions for the sample mean, the sample min, and the sample max. Use as many or as few of the lines of the tables below as you need.

Sampling Distribution of the sample min:

Outcome of the sample min

Sampling Distribution of the sample mean:

Sampling Distribution of the sample max:

Answer #1
OUTCOMES OF THE SAMPLE - MIN
PROBABILITY
0 15/16
1 1/16
OUTCOMES OF THE SAMPLE -MAX PROBABILITY
0 1/16
1 15/16
OUTCOMES OF THE SAMPLE - MEAN PROBABILITY
0 1/16
1/4 4/16
1/2 6/16
3/4 4/16
1 1/16

denominator is 16 in each case is because the total no of outcome is 16.

JUSTIFICATION: In the sample space, there is two options(0,1) for each 4 place. So, total no of outcome becomes 2*2*2*2=16.

If you need more detailed explanation, let me know in the comment section, I will surely help you. and if it helps, dont forget to upvote. Thank you.

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")...

You have decided to model an input process for a simulation study using an exponential distribution for the arrival process. From a random sample of data, you obtain the following statistics: sample mean = 25, sample variance = 529, sample median = 20, min value = 3, max value = 60. The best point estimate for the unknown parameter for this exponential arrival process is:

Statistics sampling concept 1. we sample 7groups from the population and each group has n=10,then we calculate the mean for each group . Finally, we use the mean of each group to calculate the mean . The mean should be closed to the population mean 2. we only sample one group but the n is large so the mean of that group would be close to population mean as well my question is when I should apply the first method...
