Let N=6 and n=3. For purpose of studying sampling distribution, weassume that all population values are known. In this study, two samplingplans are proposed. In Sampling Plan 1, eight possible samples are chosen.Meanwhile, in Sampling Plan 2, only three possible samples are chosen.Number of ElementPopulationin Population9912104315613041891736Sampling Plan 1: {1, 3, 5} {1, 3, 6} {1,4, 5} {1,4, 6} {2, 3, 5} {2, 3, 6}{2, 4, 5} {2, 4, 6}Sampling Plan 2: {1, 4, 6} {2, 3, 5} {1, 3, 5}(i) Compute the value of population mean.(ii)For each sampling plan, compute the value of estimated mean andbias.(iii) Which sampling plan do you think is better?

Atli believes that there is a linear relationship between the temperature in Reykjavík and the sale of mittens in his shop. He signs down the temperature in Reykjavík 7 random days and bears It compares with total sales of mittens (in krónur) the same day. The temperature measured to Average 4 degrees the days of Atli measured, with the standard deviation of 3 degrees. The total settlement sales turned out on average 28400 krónur with the standard deviation of ISK 4920. The correlation Between the mitty sales and temperature measured -0.68. How much does the mitten change when the temperature rises by one degree according to the model? Sales decreased by ISK 1115.2. The sale increases by ISK 1115.2. Sales decreased by ISK 235.7. Sales do not change. Atli wants to examine whether it is actually correlated between the mitty sales and temperature. He performs The bilateral hypothesis test and the test size in his hypothesis test is -2.07. Which resolution does he draw? He cannot…

In what is specific type of a sampling technique every 40th member of the population may particularly be selected?
I have a group with 6 members from my family.I've weight 52 kg,my father weight 63 kg,my younger brother weight 35 kg,my cousin weight 38 kg,my uncle weight 72 kg. and my eldest brother weight 55 kg.Consider samples of size 4 that can be drawin from this population. To Do: Draw the histogram for the sampling distribution of the sample means.
Withdrawal symptoms may occur when a person using a painkiller stops using it. For a certain, widely taken painkiller, withdrawal symptoms occur in 18% of people who have stopped using the painkiller. Suppose that we will take a random sample of 8 people who have stopped using the painkiller. Let p represent the proportion of people from the sample who experienced withdrawal symptoms. Consider the sampling distribution of the sample proportion p. Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed. (a) Find (the mean of the sampling distribution of the sample proportion). P H₁₁ = 1 Р (b) Find G (the standard deviation of the sampling distribution of the sample proportion). P 0₁ = P
Q1. Highlight the target population, identify the sampling technique used, and calculate the sample size for the cases listed below. Students may use Krejcie and Morgan (1979) table where required. John worked in a FMCG with 2000 employees. He calculated a sampling fraction of 1/5. Using the employee list available with HR department, he assigned each employee a unique number. John selected first employee at random from the early 5 in that list and continued to select every fifth employee onwards. Talha needed to ensure that the total of 900 staff from all the three departments of a university was represented correctly in his research. His sampling frame…
