Which of the following is not an assumption of the one-sample t-test?
a. normal distribution
b. must have a minimum number of subjects
c. independent data points
d. none of the above
Which of the following is the correct order of information of how we report the results for the t-test:
a. type of test, probability, degrees of freedom, test result
b. degrees of freedom, type of test, test result, probability
c. test result, type of test, degrees of freedom, probability
d. type of test, degrees of freedom, test result, probability
What does the t-critical value do for us?
a. this is the value that the t-test result must be larger than to allow us to know that our data is significantly different
b. this is the value that the t-test result must be smaller than to allow us to know that our data is significantly different
c. this is the value that the t-test result must be the same to allow us to know that our data is significantly different
d. None of the above
What bit of information is not needed to find the critical value for a t-value?
a. degrees of freedom
b. alpha level of test
c. one or two tailed hypothesis
d. z-score
What is the critical value of a one-tailed t-test with a degrees of freedom of df=8 and using an alpha level of .01. Fill in the blank with the probability rounded to the nearest hundredth (ex: 5.24).
t critical=[X]
If our sample mean is larger than the population, the sign of the t-value will be positive or negative and fall above or below the mean of the curve.
