All the same problem thank you When the difference between what we expect and what we observe in a study is usually large and cannot be attributed to chance, the findings is .

Which of the following statements is not true of the sampling distribution of a sample mean?

The distribtuion has a mean of
μ
¯
x
=
μ
and a standard devation of
σ
¯
x
=
σ
√
n
.

Its shape will be approximately noraml if more than 30 sample means of a given size are found.
For small samples sizes, its shape will resemble the shape of the orginal population.
It is the distribution of all possible sample means from samples of a given size.
It will be normal if the orginal population is normal.

Find the variance, standard deviation, and the range of the following dataset.

{9, 7, 8, 6, 9, 12, 11, 5, 9, 10}

Variance: 5.0, standard deviation: 2.0; range: 7
Variance: 4.7, standard deviation: 2.2; range: 7
Variance: 5.0, standard deviation: 2.2; range: 6
Variance: 5.0, standard deviation: 2.2; range: 7
Variance: 4.7, standard deviation: 2.0; range: 7
