Describe how does the distillation process works
What will be an ideal response?
The distillation process involves heating the water to boiling temperature, then cooling and collecting the vapor,
which leaves the salt behind. It is important to realize that the boiling point of water can be lowered substantially
by reducing the air pressure on the water (partial vacuum). By using a partial vacuum, the amount of heat energy
required to bring the water to a boil is reduced.

Fill in the blank(s) with correct word
A land-grant university located in the Midwest has an entering freshman class of 1 522 students. A random sample of 150, or approximately 10 percent, of the entering first- year students’ cumulative grade points were recorded. Academic standards require each student to have a first-year grade average of 1.5 or better to return for the sophomore year and 3.5 or better to be eligible for the Dean’s list. The grade point averages (GPA) below have been partially grouped.
(a) Determine the mean grade point average and standard deviation for the sample.
(b) Group the data into equal classes and construct a frequency distribution table.
(c) Draw a histogram of the distribution.
