Consider a right-tailed test (upper tail) and a sample size of 40 at the 95% confidence level. The value of t is . a. +2.023
b. -2.023
c. -1.685
d. +1.685

The correct option is d.

Step-by-step explanation:

The directional hypothesis is:

The sample size is, n = 40.

The significance level is:

The value is positive since the directional hypothesis suggests that the test is right tailed.

The correct option is d.
