II. The goal of this problem is to simulate the distribution of the sample mean. We will use the buit load the dataset and avoid some problems, copy and paste the following command in dataset 1ynx. To lynx as.numeric(lynx) Assume this vector represents the population. Le, the mean of this vector is our "true mean" (a) Draw a histogram of the population, find the "true" mean, and the true" variance. Does this data look normally distributed?...

Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.

R Programming codes for the above questions?
In the notes there is a Central Limit Theorem example in which a sampling distribution of means is created using a for loop, and then this distribution is plotted. This distribution should look approximately like a normal distribution. However, not all statistics have normal sampling distributions. For this problem, you'll create a sampling distribution of standard deviations rather than means. 3. Using a for loop, draw 10,000 samples of size n-30 from a...

For each of the following, find the mean and standard deviation of the sampling distribution of the sample mean. State if the sampling distribution is normal, approximately normal, or unknown. a. The population is skewed right with a mean of 4 and a standard deviation of 6. Many samples of size 100 are taken. b. The population is normal with a mean of 61 and a standard deviation of 9. Many samples of size 900 are taken. c. The population...

Here are three statements about the sampling distribution of the sample mean. Which of the three statements is/are true? 1. As we raise the sample size n, the sampling distribution of the sample mean has a smaller standard deviation. 2. Regardless of the sample size n, the sampling distribution of the sample mean has mean equal to the population mean. 3. The sampling distribution of the sample mean will always have the same shape as the population distribution.

Generate 20 samples of size n = 30 from your population. To do this: i. Generating a sample of just size n = 30. Calculate the sample mean, X¯, for this sample. Record this value somewhere in your spreadsheet (you will need it later). ii. Repeat the previous step 19 more times, so that you end up with a spreadsheet with 20 columns, each column has 30 randomly generated values from your population, and you have calculated a sample mean...

Which of the following statements about the sampling distribution of the sample mean, x-bar, is not true? The distribution is normal regardless of the shape of the population distribution, as long as the sample size,n, is large enough. The distribution is normal regardless of the sample size, as long as the population distribution is normal. The distribution's mean is the same as the population mean. The distribution's standard deviation is smaller than the population standard deviation. All of the above...
