Multiplechoice A.)In order to report the exact p value associated with the test statistic (result) for an independent-samples t test, we need to:

a1.)use software to obtain the value.

a2.)record the value from the t table under the 0.05 p level.

a3.)compute Cohen's d.

a4.)record the value from the t table under the 0.01 p level.

B.)The single-sample t test compares a sample mean to a population mean when:

1b.) the sample standard deviation is unknown.

2b.)no comparison can be made based on the variability in either group.

3b.)the population standard deviation is unknown.

4b.)a within-groups design is employed.

C.)In a paired-samples test, the comparison distribution is a distribution of:

c1.)mean difference scores.

c2.)raw score differences.

c3.)median distribution scores.

c4.)means.

D.)In a(n) ________, one sample is compared to a population for which we only know the mean during hypothesis testing.

d1.)single-sample t test

d2.)z test

d3.)independent-samples t test

d4.) dependent-samples t test
