A company's cereal boxes advertise that 9.65 ounces of cereal are contained in each box. In fact, the amount of cereal in a randomly selected box follows a normal distribution with mean LaTeX: \muμ = 9.70 ounces and standard deviation LaTeX: \sigmaσ = 0.03 ounces. A quality control worker selects a random sample of 5 cereal boxes. What is the standard deviation LaTeX: \sigma_{\frac{ }{x}}σ x(in ounces) of this sampling distribution?

Respuesta :

Answer:

The standard deviation of the sampling distribution    σₓ = 0.013

Step-by-step explanation:

Explanation:-

Mean of the Population  μ = 9.70 ounces

Standard deviation of the Population σ = 0.03 ounces

Given size of random sample 'n' =5

The standard deviation of the sampling distribution

               σₓ = σ/√n

            [tex]S.D = \frac{0.03}{\sqrt{5} } = 0.013[/tex]
