Bryant and colleagues (2005) did not report confidence intervals around their means and did not use confidence intervals to test any hypotheses. Let's pretend that they did. Use the hypothetical situations, below, to answer the following questions.

Question 36 of 392 Points

You can create a confidence interval around:

• A.

A sample mean

• B.

A correlation

• C.

A mean difference

• D.

All of the above

Question 37 of 392 Points

Bryant and colleagues (2005) found a significant difference in ability to savor positive experience between men and women,t(137) = 4.00,p<.001, such that women are able to savor more than men (that's actually a real finding!).

Let's pretendthey calculated a 95% confidence interval around this mean difference and obtained an interval of 1.05 to 3.46. How would you interpret this confidence interval?

• A.

We are 95% confidentthettest results are significant

• B.

We are 95% confident that the true population mean difference between men and women is between 1.05 and 3.46

• C.

We are 95% confident that there are significant differences between men and women such that men have a mean level of savoring of 1.05 while women have a mean level of savoring of 3.46

• D.

All of the above are correct interpretations

Question 38 of 393 Points

What is an alternative interpretation of this 95% confidence interval?

• A.

We are 95% confident the significant results would repeat

• B.

We areconfident that the interval would capture the true population difference between men and women in 95% of samples

• C.

We areconfident 95% of samples would show that men had an average savoring level of 1.05 and women have an average savoring level of 4.46

• D.

All are correct interpretations
