1. A population consists of the four numbers 1, 2, 4 and 5. List all the possible samples of size n = 3 which can be drawn with replacement from the population. Find the following: a. Population mean b. Population variance c. Population standard deviation. d. Mean of the sampling distribution of sample means e. Variance of the sampling distribution of sample means f. Standard deviation of the sampling distribution of sample means wid lo nem oit b nollavisedo

For the sample data set from HW M0 Problem 1: (92, 97, 88, 91, 94, 94, 85, 93, 81, 85) perform the following calculations or operations with pencil and paper: 1. Estimate the standard deviation from the range using the d2 method2. Determine the quartiles.3. Calculate the IQR. 4.Calculate boxplot 5. Sketch a stem and leaf plot.

Suppose I want to sample the household incomes for EBR parish. Let's say I start with a simple random sample of 100 residents and calculate the sample mean. How would the sampling distribution of    change if I increase the sample size to 1,000 residents?

Assume a population of 3, 4, and 11. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the nine different samples. Complete parts a through d below. 3,4 3,3 a. Find the value of the population standard deviation o. S ▼ 3,11 ▼ ■ 1 | 4,3 4,4 C (Round to three decimal places as needed.) b. Find the standard deviation of each of the nine samples, then summarize the sampling distribution of the standard deviations in the format of a table representing the probability distribution of the distinct standard deviation values. Use ascending order of the sample standard deviations. Probability (Type integers or fractions.) c. Find the mean of the sampling distribution of the sample standard deviations. The mean of the sampling distribution of the sample standard deviations is. 4,11 11,3 11,4 11,11
