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.)

Exclude leap years from the following calculations. (a) compute the probability that a randomly selected person does not have a birthday on october 4. (type an integer or a decimal rounded to three decimal places as needed.) (b) compute the probability that a randomly selected person does not have a birthday on the 1st day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (c) compute the probability that a randomly selected person does not have a birthday on the 30th day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (d) compute the probability that a randomly selected person was not born in january. (type an integer or a decimal rounded to three decimal places as needed.)
