Answer:
0.0493
Explanation:
In this case, the p-value is the probability that the value of t is greater than 1.79 with 12 degrees of freedom because the degrees of freedom are calculated as:
n - 1 = 13 - 1 = 12
Then, using a table for the distribution t, we get:
P( t > 1.79) = 0.0493
Therefore, the answer is 0.0493
