Question

Hello, please answer with either formula or preferably with TI-84 ONLY. (No rstudio, etc) thanks!

Here are the body temperatures (in degrees Fahrenheit) of 14 adults visiting a doctor’s office. (6 points) 97.7 97.8 97.9 98.1 98.198.2 98.2 98.3 98.398.5 98.5 98.7 98.9 100.2

(a) Are exact body temperatures from a population that is discrete or continuous?

(b) What is the level of measurement of body temperatures?

(c) Find the mean and median temperature from the sample above.Round answers to two decimal places, if necessary.

Answer 1

Part A answer:

Temperature is a continuous variable as it does have fractional value too

Hence, the body temperatures from a population are continuos.

Part B answer:

If you measure temperature in degrees Fahrenheit or degrees Celsius it is considered interval data because the zero points are arbitrary.

Hence, the level of measurement of body temperature is, interval scale.

Part C:

We are asked to find the mean and median temperatures.

We can find out the mean and median using the Ti84 calculator.

First of all, enter the data in the Ti84 calculator. Follow the below-given path for entering the data in the calculator.

STAT >>> EDIT >>> Edit >>> Enter.

Then, enter all the given data values in list L1.

Then, follow the below-given path,

STAT >>> CALC >>> 1-Var Stats >>> Enter.

List: L1

Keep the Freq list empty and press calculate.

You will get, mean = 98.39

And median = 98.25
