A student wants to find the answer to the question “What is the most popular restaurant in Bedford?” He asks 20 randomly selected customers at one local restaurant. Which best describes the accuracy of the results of the survey?
The survey results will be accurate since the sample was chosen randomly.
The survey results will be inaccurate since the entire population should have been surveyed.
The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.
The survey results will be accurate since the sample represents the population and the population is the target of the survey.

Explanation:</u></h3>
In a statistical study, sampling methods relate to how we choose members from the population to be in the research. If a sample isn't randomly chosen, it will reasonably be biased in some way and the data may not be representational of the population.
Efficient interpretation of data is based on real procedures for generating data and sensitive analysis of the data.The efficiency depends on how strongly the sample outlines the population. The sample must contain the attributes of the population to be representative. Here sample is chosen from one local restaurant so it willnot produce efficient analysis result.

Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Double Angle Identities: cos 2A = 1 - 2sin²A
sin 2A = 2sinA · cosA
<u>Proof LHS = RHS</u>
y cos 2A + x sin 2A = y
x sin 2A = y - y cos 2A
x sin 2A = y(1 - cos 2A)
This is a TRUE statement since it was given that
