Question

Suppose a population mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from this population of size 64. What is the standard error of the mean? What are the values of ?"̅ and ?"̅ for the sampling distribution of the mean then? Draw the curve that corresponds.

Answer #1

Solution :

Given that,

n = 64

The sampling distribution of mean is ,

_{}
= 7

The sampling distribution of standard deviation is ,

_{}
=
/
n = 9.6 /
64 = 1.2

Question 5 `
If the standard deviation of the population is 15 and the sample
size is 10,000, the standard error will be:
0
.15
.22
.43
1
points
Question 6
If you draw a sample
of 500, you can be confident that the sampling distribution of
means will:
Have a mean of
500.
Will have a standard
error of 50.
Will be heavily
skewed.
Will be a standard
normal curve.

population mean (when the standard deviation of the population is
known), what is the calculation that has to be made to obtain the
error margin? A. You multiply the number of standard deviations by
the standard deviation of the sampling distribution of sample
means. B. You subtract the sample mean from the population mean and
then divide by the standard deviation of the population. C. You
