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

(μ = 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) = 3.366,

p < 0.05 (η2 = 0.18).

assuming this test was a one-independent sample t-test, answer the following questions.

(a) is this a significant effect?

(b) what is the proportion of variance for this effect? (round your answer to two decimal places.)
