HW completion time μ=13 hr, st dev=6 hr. In a sample of 64 HW; what is p ( ẍ < 12)

The standard error of the sampling distribution of means

A sampling distribution is a collection of a large number of samples

The CLT requires _____, _____ samples.

Using Table. Assume a binomial can use normal approximation. μ = 35, std dev = 6; P(x≤30); z=

The Normal Approximation to the Binomial can be used

Consider the following sampling distribution. What does μ =?

The Central Limit Theorem is considerred

Assume a binomial can use normal approximation. μ = 35, std dev = 6; z= -0.75; P(x≤30);

We interpret the standard error of the mean as

Since the binomial is discrete, its frequency distribution will never look like a normal curve.

The mean of the sampling distribution is

In general, when calculating a point estimator using samples we

This is a ...

If a random sample is taken from a population that is normally distributed the sample will be

The correction for continuity is used for

A sampling distribution is NOT

Consider the following sampling distribution. What does the standard error of the mean =?

This is a ...

In order to use the normal to approximate the binomial μ +/- 3 std dev must

Regardless of the population, if n is large, the sample distribution will be normal because of

Bonus. This is our last question. Time is ticking....
