Question
While researching lifestyle changes to improve heart health, you come across a research article reporting that the average American consumes about 2,700 calories per day
( = 2,700).
You come across another article that refutes this, stating that a sample of Americans consumed significantly less than this mean standard on average,
t(50) = 3.132,
p < 0.05 (2 = 0.16).
Assuming this test was a one-independent sample t-test, answer the following questions.
(a) Is this a significant effect?
Yes, the effect is significant.No, the effect is not significant.
(b) What is the proportion of variance for this effect? (Round your answer to two decimal places.)
Explanation / Answer
a) Yes the result is significant
EXPLANATION:
Here P value <0.05
Hence we reject Ho.
Therefore the result is significant
b) The proportion of variance 2 = 0.16.
Interpretation: Here 2 = 0.16 >0.13
Hence there is a large effect
