The Sampling Distribution of the Mean

What happens to the sampling distribution of x̄ if the population is normal?

The sampling distribution of x̄ is also normal for any sample size n

What is the success / failure condition?

If np > 10 and nq > 10, the distribution is approximately normal.

True
False

What is the title of 8.2?
The Sampling Distribution of San Marino bullies
Population of Ms Hsu 4th period statistics.
The Sampling Distribution of the proportions
The Sampling Distribution of the Mean

μ=0.5 and σ=0.289. Let x̄ = sample mean waiting time for a random sample of 16. What is the mean and standard deviation?
X̄ = 0.72, σ = .05
I have no idea.
X̄ = 0.5, σ = .072
X̄ = 0.5, σ = .289
5
What happens to the sampling distribution of x̄ if the population is normal?
I love samples
The sampling distribution of x̄ is also normal for any sample size n
Lebron is my downpour
The sampling distribution is less symmetric
6
What is μ?
μ is the population mean
Mew
A number computed from values in a sample.
μ is the sample mean that is an estimation of x̄
7
What is the success / failure condition?
If pq > 10 and nq > 10,the distribution is approximately normal.
If np > 100 and nq > 100, the distribution is approximately normal.
If np > 10 and nq > 10, the distribution is not normal.
If np > 10 and nq > 10, the distribution is approximately normal.
8
What is the central limit Theorem?
Sage is smart
When n is sufficiently large, the x distribution is approximately normal
The more samples you have, the more accurate your probability is.
As you reach your limit, you become more self-centered

12
What is Sampling Variability?
The discrepency between the true mean and Michael Najarian.
The discrepancy between the true mean and the sampling mean
The variety of samples at costco
The discrepency between the mean and the p-value
13
What is the formula for the standard deviation of a sample mean
U=-μB=-μzB
σx̄ = σ ⁄ √n
σx̄ = √n / σ
σp̂ = √(pq/n)
14
What happens to the distribution as n increases?
The Distribution becomes more normal as n increases.
Michael becomes less normal as n increases.
Taylor becomes more normal as n increases.
The Distribution becomes less normal as n increases.
