A positive correlation (r = 0.60) is found between time spent outside at age four and creativity in kindergarten. Answer the following questions based on this result.

Describe what prediction can be made in regards to creativity in kindergarten for a child who spent a lot of time outside at age four.

Answer:

Calculate the coefficient of determination for this scenario.

Answer:

If a journalist made an error in causality when writing an article about these findings, what would they be concluding based on this scenario (one sentence is sufficient)?

Answer:

If this researcher had a sample size of 13 and started with a directional hypothesis, what was the critical r value (using the table in your textbook)?

Answer:

Should she reject or fail to reject her null hypothesis?

Answer:

If the researcher concludes that there is a relationship between time spent outside and creativity but in fact, there is NOT, what type of decision did s/he make (Type I error / Type II error, or correct decision).

Answer:

Scenario: A high school teacher believes that students who play musical instruments have better writing skills than students who do not play musical instruments.

If she wanted to test this belief (that students who play musical instruments have better writing skills than those who do not play musical instruments), what is the null hypothesis?

Answer:

What is the alternative hypothesis in this scenario?

Answer:

What is the symbolic notation for this alternative hypothesis?
