Chapter 3: Q 3.43. (page 104)

In each of Exercises 3.42-3.50, use the technology of your choice to obtain the measures of center that are appropriate from among the mean, median, and mode. Discuss your results and decide which measure of center is most appropriate. Provide a reason for your answer. Note: If an exercise contains more than one data set, perform the aforementioned tasks for each data set.

U.S. Hospitals. The American Hospital Association conducts annual surveys of hospitals in the United States and publishes its findings in AHA Hospital Statistics. Data on hospital type for U.S. registered hospitals can be found on the WeissStats site. For convenience we use the following abbreviations:

  • NPC: Nongovernment not-for-profit community hospitals
  • IOC: Investor-owned (for-profit) community hospitals
  • SLC: State and local government community hospitals
  • FGH: Federal government hospitals. NFP: Nonfederal psychiatric hospitals.
  • NLT: Nonfederal long-term-care hospitals.
  • HUI: Hospital units of institutions

Short Answer

Expert verified

The mode of the given data is NPC and the mode is a suitable measure of center.

Step by step solution

01

Step 1. Given information.

The given statement is:

The data of different hospitals is provided here.

02

Step 2. Determine the most suitable center measure.

Data on hospitals is available here.

The frequency distribution is as follows based on the given data and the DDXL.

The given data is qualitative data so the appropriate measure of center is MODE. Mode is the value that occurs with the greatest frequency in the data set.

From the above output, the group NPC has the greatest frequency of 2919. So the best measure of center for the given data is the mode, which is 2919.

Augusta National Golf Course. Earlier in this section, we found that the population standard deviation of the lengths of the holes at the Augusta National Golf Club is 132.0yd. In this context. is the number 132.0a parameter or a statistic? Explain your answer.

Iron is essential to most life forms and to normal human physiology. It is an integral part of many proteins and enzymes that maintain good health. Recommendations for iron are provided in Dietary Reference Intakes, developed by the Institute of Medicine of the National Academy of Sciences, The recommended dietary allowance (RDA) of iron for adult females under the age of 51is 18milligrams (mg) per day. The iron intakes during a 24-hour period for a random sample of45 adult females under the age of 51have a mean of 14.7mgand standard deviation of 3.1mg.

a. Construct a graph .
b. Apply Chebyshev's rule with k=2 to make pertinent statements about the observations in the sample.
c. Repeat part (b) with k=3.

A quantitative data set has size 50. At least how many observations lie within three standard deviation to either side of the mean?

Body mass index (BMI) is a measure of body fat based on height and weight. According to the document Dietary Guidelines for Americans published by the U.S. Department of Agriculture and the U.S. Department of Health and Human Services, for adults, a BMI of greater than 25indicates an above healthy weight (i.e., overweight or obese). The BMIs of 75randomly selected U.S. adults have a mean of 26.0and a standard deviation of 5.0
