If the sample is used for a hypothesis test, what does the null hypothesis (Ho) put forth about the treatment? O The treatment has an effect on anxiety. O The treatment divides each anxiety score by a constant. O The treatment multiplies each anxiety score by a constant. The treatment has no effect on anxiety.

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 58 of 100 individuals prefer Brand A. Complete parts a through c.
