The elevatiori we call sea level is actually the average level of the sea This means that at average sea kevel, the elevation is zero In reality, the level of the sea rises and fals in what are called tides. Low tide is the point of lowest sea level in a tidal period, High tide is the point of highest sea level ina tidal period. The height above ar below average sca level is caled elevation. An elevation below soa level is consiiered a negative value, whie an elevation above sea level is positive Winston lives near the acean. He rejgularly brings an altimeter to the beadh to measure the elevation of the ocean's surface, You will use the data Winston gathered to cormplete tasks about the rising and falling of the ocean's surface. When necessary, sketch a diagram of the stuation on a separare sheet of paper to assist you. On Monday at 1 p. m., when the ocean's surface was at an elevation of 22 feet, Winston went to surf shop that was 82 leet above the ocar's surface AL7p. m. when the ocean's surface was at an elevation of 24 feet, Winston ate dinrier at a restaurant whose deck was 10 feet above the oceans surface. Part A The ocean went down 4.6ft from 1pm to 7pm.

Part B QUESTION: How many feet apart are the two ocean elevations described in part A?​

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
