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
