List all possible samples of size n=3, with replacement, from the population (1,3,5). Calculate the mean of each sample. Construct a probability distribution of the sample means and compute the mean, variance, and standard deviation of the sample means and compare to the mean, variance, and standard deviation of the population.

For the small population, systemically list all of the possible samples of size n=3 that can be selected by drawing 3 units from 5 with equal probability without replacement. y1 = 6 y2 = 2 y3 = 5 y4 = 12 y5 = 10

The sampling distribution of means is: A list of all members of the population you are studying. Also called the standard error of the mean. A set of numbers representing all of the possible sample means on a variable you could draw from a given population and a given sample size. A list of all members of the sample that you draw. 1 points Question 2 The standard deviation of the sampling distribution of means is called the: Margin of...

Suppose we roll a fair die two times; consider all the combinations of the numbers from each of the two rolls. (a) How many different samples are there? No of samples 36 (b) Consider each of the possible samples. Compute the mean and the standard deviation of all sample means and the distribution of population. (Round mean values to 1 decimal place and standard deviation values to 3 decimal places.) Consider using Excel as a time saver to show all...

1. How many permutations are possible when taking samples of 3 from a population of 20? 2. How many combinations are possible when taking samples of 3 from a population of 20? 3. a researcher asked 15 samples of size (n=100) about their television use. The mean (M) reported number of television use per hour for each sample is below 5,6,8,10,13,15,20,22,23,25,27,33,39,42,60 What is the best estimate for the population mean? Give actual value 4 Here are the standard deviation for...

python code The power set of a list L is a list containing all possible combinations of the elements of L. For example, the power set of [1, 2, 3] is [[], [1], [2], [3], [1, 2], [1, 3], [2, 3], [1, 2, 3]]. Section 9.3 of your textbook describes a (subtle) algorithm for generating the power set. • Read and understand the structure of the code in Figure 9.6 • Write (your own) function powerset(L) that generates and returns...
