Answer the following questions (1/2 point each, 4 points total): a. When should we use a t-test? b. When should we use a single-sample t-test? c. Why do we calculate standard deviation using N-1 rather than N like we used to? d. What is the standard error of the mean? e. Does it get larger or smaller as our sample size increases? Why? f. Does the critical value of t (i.e, the score you need for your results to be...

Each of these problems (Problems 1-4) is worth four points Definition: Two lines or curves are said to be normal to each other at their point of intersection if they intersect there at right angles or, equivalently, if their tangent lines at the point of intersection are 1. A well-known theorem in geometry states that a line which is tangent to a circle is perpendicular to the radius of the circle at the point of tangency. Use implicit differentiation to...
