Determine the analysis and state the null and alternate hypothesis.

Find out what analysis would you do on each problem (i.e., one-sample z-test, one-sample t-test, proportion test, two-sample independent t-test, or paired test)?  Then state the null and alternative hypothesis for a problem.

a. A new training method has been developed for typing speed.  To see if the training increases typing speed, managers measured the typing speed of 20 support staff and then send them through the training.  After the training is over, the staffs are timed again.
