15. A test of significance is to be carried out with hypotheses H₀: = 36 vs. H_a: < 36 based on data from a simple random sample selected from a normally distributed population variable. It was decided to use a level of significance of = 0.02 to decide whether or not to reject the null hypothesis. The sample data produced a standard deviation of 15.6 based on 12 sample values. If the p-value for the test is 0.067, what is the appropriate conclusion?

Group of answer choices

Reject H₀, there is sufficient evidence to conclude the mean is less than 36.

Fail to reject H₀, there is sufficient evidence to conclude the mean is less than 36.

Fail to reject H₀, there is insufficient evidence to conclude the mean is less than 36.

Reject H₀, there is insufficient evidence to conclude the mean is less than 36.
