Claim: The mean student loan debt for Fresno State graduates is greater than $22,735. Results of a survey of 40 recently graduated students from Fresno State showed that their mean student loan debt was $26,841. Assuming that σ = $18,307, find the value of the test statistic.  Round your answer to two decimal places, if needed.
