P value is the probability that the results were do solely to chance. P = .05 means that the probability that the results were due solely to chance were 5 times in 100. Depending on your tolerance for occurring by chance, you will reject the null hypothesis if P is too small.
For P ≤ .05, the t value with 27 df = 2.052.
df = n - 1
use technology to find the P-value for a two tailed test with n=28 and a test statistic t=2.032
P-value =????
