19. What is the average amount of time a PA teenager spends per day at the beach? We are 95% confident that the interval for the population mean of hours spent on the beach per day is between 4.808 and 5.82057 hours. In recurring samples of the same size (n=70), the true average of hours spent on the beach per day will catch the interval 95% of the time.

20. Overall Conclusions Overall, PA teenagers favor Ocean City and Wildwood over the other Jersey Shore Points – When asking common activities, boardwalk was often chosen Pizza was the most liked “shore food” among PA teenagers The distribution of visited shore points, shore foods, and activities at the shore are not uniformly distributed among PA teenagers

21. Application to Population The population at large could use our information – Hot spots for vacationers – Most common things to eat on vacation – Fun activities to do when at the shore

22. Possible Bias & Error Response Bias – Online survey Respondents may have fabricated their answers because other people could read them Voluntary Response – Drexel Class of 2015 Facebook Group Asked for responses from Pennsylvanian Teenagers Respondents had the option whether they wanted to answer Undercoverage – We had 212 responses, but we only took every three so we had 70 subjects Decent population, but there may not be a lot of variability
