p < 0.0805 (2tailed)
For a 2tailed test, the
pvalue represents the probability of making a type 1 error (concluding there is
statistical significance when there is none). Since
there is about 8% chance of making a type 1 error, which exceeds the 5% error limit
established in the rejection criteria of the hypothesis testing process (alpha), you would
not conclude there is statistical significance.
