The salinity, or salt content, in the ocean is expressed in parts per thousand (ppt). The number varies due to depth, rainfall, evaporations, river runoff, and ice formation. During January and February, the mean salinity in a region of the northeast continental shelf was 34.08 ppt. The distribution of salinity is normal and the standard deviation is 0.52 ppt. Suppose a random sample of ocean water from this region is obtained. Sketch a graph for each situation.

a)What proportion of the ocean water has salinity more than 35 ppt?

b)Find the salinity that corresponds to the third quartile
