2. You want to propose your long time best friend. But you are scared to do so fearing rejection. Since both of you are statistics freaks, you gave your best friend two statements, one representing null hypothesis and the other representing alternate hypothesis. The rejection of null by your best friend would mean that your proposal is accepted. Write the null and alternate hypothesis statements. How will you define Type-I error and Type-II error in this case?

Why is the phrase “goodness of t” used to describe the type of hypothesis test considered in this section?
What is the name of this hypothesis test? One technique to help people deal with phobias is to have them counteract the feared objects by using imagination to move themselves to a place of safety. In an experimental test of this technique, patients sit in front of a screen and are instructed to relax. Then, they are shown a slide of the feared object (for example, a picture of a spider). The patient signals the researcher as soon as feelings of anxiety begin to arise, and the researcher records the amount of time that the patient was able to endure looking at the slide. The patient then spends two minutes imagining a "safe scene" such as a tropical beach or a famniliar room before the slide is presented again. Again the patient signals at the first feelings of anxiety and the researcher records the amount of time that the patient was able to endure looking at the slide. If we could see the data, we can ask if the data indicate that the imagination technique effectively alters phobias.…
