Random Sampling Methods & Statistical Investigation Stages
Methods of Random Sampling & Stages of Statistical Investigation
Definitions
Sampling: The process of selecting a representative subset of individuals (a sample) from a larger set (a population) to accurately estimate the characteristics of the whole population.
Random Sampling: A sampling method where each member of the population has an equal and independent chance of being selected, ensuring a representative sample.
Random sampling allows for incomplete investigations, eliminating the need to

RESCUE AND SHIP REFLOATING
CALCULATION OF TIDES for refloating
This guide explains how to calculate tides for rescue and ship refloating operations.
DEFINITIONS:
- DM: Duration of the trip (time between high and low tide)
- HP: Height of high tide
- HB: Height of low tide
- A: Amplitude of the tide (difference between high and low tide)
- Sc: Probe letter (depth measured from the water surface to the seabed)
- PRF.REAL: Real depth (actual depth of the water, considering the tide)

Understanding Queuing Systems
DMV Branch Scenario
A DMV branch with one waiting line and multiple agents serving customers experiences an arrival rate of 12 customers per hour. The average service time per customer is 48 minutes, and each agent works 80% of the time. To determine the number of agents needed, we can use queuing theory principles.
