Suppose a highlighter manufacturer wanted to find out whether a highlighter lasted longer than the claim of 14 continuous hours. They tested 40 highlighters and recorded the number of continuous hours the highlighter wrote before drying up. Test the hypothesis that the highlighters wrote more than 14 hours. Following are the summary statistics. x bar=14,5 hrs, s= 1.2 hours. Report the test statistic, p-value, the null hypothosis decision. At the 5% significannce level, state your conclusion about the original claim.

A) 0.023

B) 0.155

C) 0.345

D) 0.477
