A rollercoasters auditors estimate that the average daily. A Rollercoaster''s auditors estimate that the average daily loss from those illegally riding without tickets is at least(greater or equal) $295, but wants to determine the accuracy of this statistic. the company researcher takes a random sample of losses over 64 days and finds x=$300 and s=$15.

a) test at a=0.05

b)Construct a 94% confidence interval of losses. Note a and b are independent
