If the points are close to one another and the width of the imaginary oval is small, this means that there is a strong correlation between the variables

When there is no linear relationship between two variables, the correlation coefficient is _____.

To evaluate the sample mean against the hypothesized population mean, we use the concept of z scores to determine how different the two means are.

It simply means two variables.

This level indicates the level of assurance you have that the resulting confidence interval encloses the unknown population mean.

A hypothesis that defines a specific value of the population parameter that is of interest.

It is the amount that is added to and subtracted from the mean to construct the confidence interval.

We establish critical regions based on ________________.

These are the factors that affect the power of a test.

The null hypothesis is false and we accept it.
