1. Explain why you would conduct a t test rather than a z test. In other words, what is the difference between a one sample t test and a one sample z test? 2. Because of what is discussed in question 1, some of the components of calculating at value are different from the components of a z value. Specifically, the t value utilizes degrees of freedom. Explain what degrees of freedom means (you can include...
