B) Between 0.02 and 0.05
C) Between 0.05 and 0.10
D) Between 0.10 and 0.20
E) Larger than 0.20
Two Tailed Test
A statistical test that evaluates the possibility of a relationship in both directions, allowing for the rejection of a null hypothesis for extreme values at either end of the probability distribution.
Test-statistic
A value calculated from sample data during a hypothesis test, used to determine whether to reject the null hypothesis.

Final Answer :
D
Explanation :
The p-value for a two-tailed test can be found using a t-distribution table or software, given the test statistic (1.55) and degrees of freedom (n-1 = 29-1 = 28). For a t-value of 1.55, the p-value falls into the range between 0.10 and 0.20, indicating it is not highly significant.
