Hi Can you help with this assignment, I was trying to figure it out on my own, but I don't know if I am answering the following questions correctly, because I am not familiar with how to use RStudio, I am just learning how to use it. Please explain each of the questions below correctly and briefly.
You have to use R-Studio to answer these questions:
1)Take a random sample of size 50 from the price. Using this sample, what is your best point estimate of the population mean?
2)Since you have access to the population, simulate the sampling distribution for xpricexprice by taking 5000 samples from the population of size 50 and computing 5000 sample means. Store these means in a vector called sample_means50. Plot the data, then describe the shape of this sampling distribution. Based on this sampling distribution, what would you guess the mean home price of the population to be? Finally, calculate and report the population mean.
3)Change your sample size from 50 to 150, then compute the sampling distribution using the same method as above, and store these means in a new vector called sample_means150. Describe the shape of this sampling distribution, and compare it to the sampling distribution for a sample size of 50. Based on this sampling distribution, what would you guess to be the mean sale price of homes in Ames?
4)Of the sampling distributions from 2 and 3, which has a smaller spread? If we're concerned with making estimates that are more often close to the true value, would we prefer a distribution with a large or small spread?
Here below I am also attaching screenshot files that contain the instructions that can help you with the 4 questions using RStudio.
