Assume that the following data represent baseball batting averages for a random sample of National League players near the end of the baseball season. Make a dotplot for the data. At Westgate Community College, a survey was done to determine when students are available for class.
A questionnaire was given to a random sample of students. The instructions were to mark each of the time categories in which they could take classes. Many students marked more than one category.
Responses from the students in the sample indicated that 52 would take early morning classes, 85 would take mid-morning classes, 41 would take afternoon classes and 37 would take evening classes.
Would a circle graph be appropriate for this data? Give a reason for your answer. Since there were multiple responses from some students this data does not represent parts of a whole. There are too few categories for a circle graph to be useful.
C Yes. Circle graphs are most effective when the number of wedges is 10 or fewer. D Yes. Each category represents a percentage of the total student population that could attend class at a certain time. E Yes. The categories represent all possible responses. Suppose you decide to take the summer off and sign on as a deck hand for a commercial fishing boat in Alaska that specializes in deep-water fishing for groundfish. What kind of fish can you expect to catch? One way to answer this question is to examine the reports on groundfish caught in the Gulf of Alaska.
The following list indicates the types of fish caught annually in thousands of metric tons: flatfish, Make a Pareto chart showing the annual harvest for commercial fishing in the Gulf of Alaska. A survey of adults uncovered some interesting housekeeping secrets. When unexpected company comes, where do we hide the mess? Make a circle graph to display this information. It is a beautiful desert lake famous for very large trout.
The elevation of the lake surface feet above sea level varies according to the annual flow of the Truckee River from Lake Tahoe. Assume that the U. How long did real cowboys live? This delightful book presents a thoughtful sociological study of cowboys in West Texas and Southeastern New Mexico around the year Assume that a sample of 32 cowboys gave the following years of longevity: 58 92 Make a stem-and-leaf display for these data.
Wetlands offer a diversity of benefits. They provide habitat for wildlife, spawning grounds for U. In the last years the United States has lost more than half its wetlands. Suppose Environmental Almanac gives the percentage of wet lands lost in each state in the last years.
Assume that for the lower 48 states, the percentage loss of wetlands per state is as follows:. The distribution is approximately mound shaped. Suppose the American Medical Association Center for Health Policy Research included data, by state, on the number of community hospitals and the average patient stay in days in its publication.
The data by state are shown in the table. Which two states have an unusually high number of hospitals? State Alabama Alaska Arizona Arkansas.
