You want to estimate the average salary of nurses at the Texas Children's Hospital. You randomly select 10 nurses and ask them their salary. To construct a 95% confidence interval for the average salary of nurses, you will need:

The appropriate z-value from the standard Normal distribution.

The appropriate t-value from the student distribution with 9 degrees of freedom.

The appropriate t-value from the student distribution with 10 degrees of freedom.

The appropriate t-value from the student distribution with 11 degrees of freedom.
