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
