1. Which of the following is not an assumption of the one-sample t-test?

• normal distribution
• must have a minimum number of subjects
• independent data points

2. A marine mammal researcher has taken fecal samples from every dolphin in captivity to test for possible parasites. What should they report when presenting the findings?

• standard deviation
• standard error of the mean

3. Which of the following is the correct order of information of how we report the results for the t-test:

• type of test, probability, degrees of freedom, test result
• type of test, degrees of freedom, test result, probability
• test result, type of test, degrees of freedom, probability
• degrees of freedom, type of test, test result, probability

4. If your t-test value is t=3.45 and the critical value is CV=3.46, your data is

• significantly different
• not significantly different

5. What does the t-critical value do for us?

• this is the value that the t-test result must be larger than to allow us to know that our data is significantly different
• this is the value that the t-test result must be smaller than to allow us to know that our data is significantly different
• this is the value that the t-test result must be the same to allow us to know that our data is significantly different
• None of the above
