In a statistical study at a hospital emergency room, body temperatures of patients are taken using an oral thermometer when they enter the hospital on March 15, 2020. A sample of the temperatures of 16 patients is listed below. The temperatures are recorded in degrees Fahrenheit.

98.2 98.6 98.9 99.5 100.7 97.9 101.1 98.3

98.1 99.3 98.7 102.2 100.3 98.9 98.0 100.4

Questions - SET 1:

Find the mean of the set of temperatures.

Find the median of the set of temperatures.

Find the mode of the set of temperatures.

Find the maximum, minimum, and range of the set of temperatures. (Range is defined as the difference between the maximum and minimum temperatures in Section 6B.)

Which one of the temperatures might be considered an outlier?

SET 2:

If the above 16 temperatures are a subset of all the patients entering the hospital emergency room on March 15, 2020, found by recording the temperature of every 5^th patient who enters, what type of sampling method was used?

The 16 people whose temperatures were recorded comprise the sample for this study. What was the population?

The sample size for the statistical study is n=16. What is the population size for this study? That is, how many patients entered the emergency room on this day (March 15, 2020) assuming that the temperatures of every 5^th person were recorded?

What is a sample statistic for this study?

What is a population parameter for this study?

If the margin of error for the mean body temperature is 0.52 degrees Fahrenheit, what is the Confidence Interval?

Is this statistical study an experiment or an observational study?

SET 3:

You should make a Frequency Table and a Histogram for the data (see Section 5C) according to the bin pattern, 97.0-97.9, 98.0-98.9, ..., before answering the following questions.

If the data is grouped into bins according to the following pattern, 97.0-97.9, 98.0-98.9, ..., how many bins would be needed?

What would the frequency be of the 99.0-99.9 bin?

Of all the bins, which would be the mode?

Which bin contains the mean?

What is the shape of this distribution of temperatures (the shape of the histogram): symmetric, right-skewed, or left-skewed?
