What is the critical t-value for each of the following scenarios use (t-distribution and assume “gold standard” p-value; each blank worth 1 point):
a. N = 43, one-tailed Independent Samples t-test --> Critical t-value is __________.
If calculated t = 2.00, what is your decision regarding the null: __________.
b. N = 35, two-tailed Paired Samples t-test --> Critical t-value is __________.
If calculated t = 2.00, what is your decision regarding the null: __________.
Solutions
Expert Solution
Since the level of significance is unavailable , I assume it as 95%. then the critical values are calculated using the T-table shown below at respective degree of freedoms.
a. N = 43, one-tailed Independent Samples t-test --> Critical t-value is -1.68 if it is a ledt tail test, and + 1.68 if it is a right tailed test.
Now if calculated t = 2.00, the if the test is right tailed test then Reject The null hypothesis.
and if Left tailed test then fail to reject,.
b.N = 35, two-tailed Paired Samples t-test --> Critical t-value is 2.03
If calculated t = 2.00, the failed to reject the null hypothesis , since The Calculated T < t critical.

The Student's t distribution table gives critical values for the
Student's t distribution. Use an appropriate d.f. as the row
header. For a right-tailed test, the column header is the value of
α found in the one-tail area row. For a left-tailed test, the
column header is the value of α found in the one-tail area row, but
you must change the sign of the critical value t to −t. For a
two-tailed test, the column header is the value...
