In each Exercises 3.82-3.90, use the technology of your choice to determine and interpret the range and sample standard deviation for those data sets to which those concepts apply. If those concepts don't apply, explain why. 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

Step by step solution

01

Step 1. Given information.

The given statement is:

The given categories are NPC, IOC, SLC, FGH, NFP, NLT, and HUI.

02

Step 2. Determine the data's range and standard deviation.

Range$=max-min$

Standard Deviation:

$s=\sqrt{{\displaystyle \frac{∑{x_i}^2-{\left(∑x_i\right)}^2/n}{n-1}}}$

The categories are NPC, IOC, SLC, FGH, NFP, NLT, and HUI, it is a qualitative variable.

Finding the range and standard deviation is not possible for this data.

And to be able to find the range and standard deviation require numerical data, and hence a quantitative variable, for the provided data set.
