Step 1 of 5) Discuss the benefits of having trained interviewers. Making an Informed Decision Suppose you have just received a $1000 bonus at your job. Rather than waste the money on frivolous items, you decide to invest the money so you can use it later to buy a home. You have many investment options. Your family and friends who have some experience investing recommend mutual funds. Which fund should you choose See the Decision project on page 522. PUTTING IT TOGETHER In Chapter 9, we mentioned there are two types of inferential statistics: (1) estimation and (2) hypothesis testing. We have already discussed the procedures for estimating the population proportion, the population mean, and the population standard deviation. We now focus our attention on hypothesis testing. Hypothesis testing is used to test statements regarding a characteristic of one or more populations. In this chapter, we will test various hypotheses regarding a single population parameter.
