I need detailed and complete solution please for me to understand how the answer arrived. Thankyou

Please read instruction as stated in the pic:

by using the appropriate probability sampling technique.

Please skip #3.

Instructions: Read and analyze each item carefully. Solve the following word-problems by using the appropriate probability sampling technique. Due to the pandemic that we are experiencing right now, a researcher (w/ IATF permit) aims to determine the health status of the senior citizens in a certain municipality. The barangays in the municipality have a total population of 11, 926 senior citizens. Determine how many senior citizens will constitute the sample if the margin of error is 1%, 5%, and 10% respectively. Which among these confidence levels is the most reliable and valid to represent the population? And Why? 1. A researcher aims to determine the health status of the senior citizens in a certain municipality. The 60 barangays in the municipality has a total population of 73,528 senior citizens. Determine how many senior citizens will constitute the sample if the margin of error is 5% Determine the 2"d, 9", and 17" units in the sample using the table of random numbers given below. 33658965431 65823648362 37354271383 43538463782 83906213564 2. The researcher wants a systematic sampling and the sample size is 98. Determine the following: a. The Sampling interval b. The first two units in the sample if the random start is 2 c. The middlemost unit's in the sample if the random start is 5 d. The last two units in the sample if the random start is 3 3. A researcher wants a sample size of 1200 to be drawn from the population which is divided into three strata size N = 8000, N, = 4800 and N;= 3,200. Determine the sample sizes for the different by adopting proportional allocation A population is divided into three strata so that N,= 10, 000 N2= 4,000 and Na= 6,000. Respective standard deviation are (1= 5, (2=20, @;=10. How should a sample size of n = 320 be allocated to the three strata if the researcher wants optimum allocation using disproportionate sampling design
