In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft. For a group of 1013 adults, the mea
Kazeer [188]

Answer:

Mean = 344

Step-by-step explanation:

Given

Population =  1013

Let p represents the proportion of those who worry about identity theft;

p = 66\%

Required

Mean of those who do not worry about identity theft

First, the proportion of those who do not worry, has to be calculated;

Represent this with q

In probability;

p + q = 1

Make q the subject of formula

q = 1 - p

Substitute p = 66\%

q = 1 - 66\%

Convert percentage to fraction

q = 1 - 0.66

q = 0.34

Now, the mean can be calculated using:

Mean = nq

Where n represents the population

Mean = 1013 * 0.34

Mean = 344.42

Mean = 344 (Approximated)

Which of the following statements is not true? a) The standard deviation of the sampling distribution of sample mean = σ/√n b) T
I am Lyosha [343]

Answer:

e) The mean of the sampling distribution of sample mean is always the same as that of X, the distribution from which the sample is taken.

Step-by-step explanation:

The central limit theorem states that

"Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases."

This means that as the sample size increases, the sample mean of the sampling distribution of means approaches the population mean.  This does not state that the sample mean will always be the same as the population mean.
