Question:

To increase sales, Honey Nut Cheerios decided to include a toy action figure inside some of their boxes. The company claims that an action figure can be found in 20 percent of the boxes. However, based on their experiences eating this cereal at home, a group of students believes that the proportion of boxes with action figures is less than 0.2. This group of students purchased 75 boxes of the cereal to investigate the company's claim. The students found a total of 10 action figures in the 75 boxes. Suppose it is reasonable to assume that the 75 boxes purchased by the students are a random sample of all boxes of this cereal. Based on this sample, is there support for the students' belief that the proportion of boxes with action figures is less than 0.2? With an alpha level of 0.1, provide statistical evidence to support your answer. Edit View Insert Format Tools Table 12pt ~ Paragraph
