Six measurements were made of the magnesium ion concentration (in parts per million, or ppm) in a city’s municipal water supply, with the following results. It is reasonable to assume that the population is approximately normal. Based on a 98% confidence interval for the mean magnesium ion concentration, is it reasonable to believe that the mean magnesium ion concentration may be greater than 195? (Hint: you should first calculate the 98% confidence interval for the mean magnesium ion concentration.)

Part 5: Oceanography and the real world [10 points]Please answer ONE of the questions below. Do not do both of them, please! Just one.     (1) Surfers come from all around the world to surf at Rincon Point near Santa Barbara. Below, there is an aerial view of Rincon Point. (You can ignore the “cove”, “river mouth”, and “indicator” labels.)  Take a couple of minutes and sketch the diagram (it doesn’t have to include every detail–just the general shape of the land and location of land vs. ocean.) Using the diagram, provide a clear oceanographic explanation of why Rincon Point is such a sweet surf spot.     (2) You’re planning to go to Cabrillo Beach over the Thanksgiving holiday for tidepooling. The Cabrillo Beach tidetables are below. Based on your knowledge of tides: In general, which day (Thursday 25, Friday 26, Saturday 27, or Sunday 28) would be the BEST for tidepooling? (Pick one.) How did you decide? Will tidepooling on the day that you picked be better in the morning, afternoon, OR evening? (Pick one.) How did you decide? Yes OR no—should the tidepools be better exposed a week later (week of December 2 )? How do you know? Which day has the largest range between high tide and low tide? What is the range between high and low tide on this day? Tides for Cabrillo Beach starting with November 25, 2021.
