Question

Use SPSS for this Application Exercise:
A nurse at a health clinic hypothesizes that ear thermometers measure lower body temperature than oral thermometers. The nurse selects a sample of healthy staff members and took the temperature of each with both thermometers. The temperature data are below. What can the nurse conclude with an α of 0.01?

ear	oral
97.8 98.6 98.9 97.9 99.1 98.2	97.4 97.3 96.3 97.4 98.1 97.7

b)
Condition 1:
---Select--- staff members oral thermometer ear thermometer health clinic body temperature
Condition 2:
---Select--- staff members oral thermometer ear thermometer health clinic body temperature

c) Input the appropriate value(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

d) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r² =  ;   ---Select--- na trivial effect small effect medium effect large effect

e) Make an interpretation based on the results.

The ear thermometer measured significantly higher temperatures than the oral thermometer.The ear thermometer measured significantly lower temperatures than the oral thermometer.    There was no significant temperature difference between the ear and oral thermometer.

Answer 1

b)
Condition 1:
ear thermometer
Condition 2:
oral thermometer

c) Input the appropriate value(s) to make a decision about H₀.

p-value = 0.0138; Decision: Fail to reject H0

d) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d = 1.256;    large effect
r² = 0.654; large effect

e) Make an interpretation based on the results.

There was no significant temperature difference between the ear and oral thermometer.
