The article claimed that typical supermarket trip takes mean of 22 minutes. Assume that in effort to test this claim, you select sample of 50 shoppers at local supermarket. Mean shopping time for sample of 50 shoppers is 25.36 min. with standard deviation of 7.24 minutes. Using 0.10 level of significance is there evidence that mean shopping time at local supermarket is different from claimed value of 22 minutes?
