Chapter 1: Q 19. (page 25)

Going to school Students in a high school statistics class were given data about the main method of transportation to school for a group of 30 students. They produced the pictograph shown. Explain how this graph is misleading.

Short Answer

Expert verified

The various keys do not correspond to the same number of people who use this mode of transport.

The pictogram's widths don't match the number of people in the key.

Step by step solution

01

Step 1. Given information.

The given pictogram is:

02

Step 2. Explanation.

With the provided pictogram, there are two major issues:

The first problem is that different keys correlate to different numbers of people. Because each pictogram represents a different amount of people using this mode of transportation, it will look that an equal number of people are using the bus as opposed to cycling when we just have one pictogram for each.

The second problem is that the pictogram's widths don't match the number of people in the key.

The width of the automobile pictogram, for example, is roughly two times that of the walk pictogram, despite the fact that they both correspond to two people.

Healthy cereal? Researchers collected data on 76 brands of cereal at a local supermarket. 27 For each brand, the sugar content (grams per serving) and the shelf in the store on which the cereal was located (1 = bottom, 2 = middle, 3 = top) were recorded. A dotplot of the data is shown here.

Part (a) Is the variability in sugar content of the cereals on the three shelves similar or different? Justify your answer.

Part (b) Critics claim that supermarkets tend to put sugary cereals where kids can see them. Do the data from this study support this claim? Justify your answer. (Note that Shelf 2 is at about eye level for kids in most supermarkets.)

Risks of playing soccer (1.1) A study in Sweden looked at former elite soccer players, people who had played soccer but not at the elite level, and people of the same age who did not play soccer. Here is a two-way table that classifies these individuals by whether or not they had arthritis of the hip or knee by their mid-fifties:

Part (a). What percent of the people in this study were elite soccer players? What percent of the people in this study developed arthritis?

Part (b). What percent of the elite soccer players developed arthritis? What percent of those who got arthritis were elite soccer players?

Part (c). Researchers suspected that the more serious soccer players were more likely to develop arthritis later in life. Do the data confirm this suspicion? Calculate appropriate percentages to support your answer.
