Oceаnоgrаphers interested in the effects оf rising temperаtures glоbally found historical data of ocean temperatures off Cabo San Lucas from the 1950s. In order to test the hypothesis that water temperatures have risen since then, they repeated the measurements from the years 2000-2010. Ocean temperature was measured at a coastal station on January 1 of every year from 1950 to 1960, and again from 2000-2010. The data are presented here in a graph format with standard deviations represented by the error bars. Accessible description of imgae:  Bar chart titled “Average Ocean Temperatures” with the y-axis labeled “Average Temperature (°F)” ranging from 40 to 80 degrees. Two bars compare time periods 1950–1960 and 2000–2010. The 1950–1960 bar is just under 70°F, while the 2000–2010 bar is slightly above 70°F, with small error bars shown on both bars, indicating a slight increase in average ocean temperature over time.   What was the approximate mean ocean temperature 1950-1960?
