For a right-tailed test of a hypothesis for a population mean with n = 14, the value of the test statistic was t = 1.863. The p-value is:
A)between .05 and .025.
B)between .10 and .05.
C)greater than .10.
D)less than .01.

The p-value is the probability of observing a test statistic as extreme as, or more extreme than, the observed value under the null hypothesis. For a t-test with n = 14 (which means 13 degrees of freedom), a t-value of 1.863 falls between the critical values for p = .05 and p = .025 in the t-distribution table, indicating the p-value is between these two values.
