## Sample testing when we don’t know the Population Standard Deviation

Sample Testing When We Don’t Know The Population Standard Deviation Its all well and good sample testing when we know the population standard deviation. But what about if we don’t have the ability to get production data, or we just have a small sample size? How to conduct sample testing when we don’t know the

## Calculating Hypothesis Test Statistics

In this blog post, we will continue our Hypothesis testing example and will be Calculating hypothesis test statistics. Lets actually work with some numbers! From our 3 previous blog posts: Creating a Hypothesis For Sample Testing Deciding the Correct Hypothesis Sample testing in China- hypothesis rules We have the following: Null hypothesis, H0= All bags

You can find them here: Creating a Hypothesis For Sample Testing Deciding the Correct Hypothesis From the above, we developed the hypothesis:

In this blog post, we discuss creating a hypothesis for sample testing.  We should probably start at the beginning.  What is a Hypothesis Test?  A hypothesis is an idea or explanation that is proposed, the

## The Real Cost of Shipping From China

## The Z score and How We Can Use it in Acceptance Sampling

The Z Score And How We Can Use It In Acceptance Sampling In our last blog post, we talked about how Standard deviation can allow us to understand if data points are away from the mean and by how much. In this post, we are going to discuss how we can calculate the Z score

## The Importance of sample size

We spoke in our past blog about what a sample is, and what are the best way of obtaining random sampling subgroups for testing. In this post, we will be discussing the importance of sample size.  Sample Size We briefly said in our previous post that Bigger = Better and this is the case. A
