[answerhappygod]

In Section 1, all class bounds for the Age histogram should be
integers, and the class bounds for the FEV1 histogram should be
rounded to three decimal places.
Section 1 – Visual Data Assessment. For each variable of
interest – Age and FEV1 – create a grouped frequency histogram. For
Age, use a "Start at:" value of 3 and a "Width:" value of 2; for
FEV1, use a "Start at:" value of 0.750 and a "Width:" value of
0.500. Each histogram must include an informative title, along with
correct labels for both axes. It is not necessary to display
frequency counts above the bars. For each histogram, include a
paragraph that answers each of the following questions:
Is the histogram symmetric, left-skewed, right-skewed, or
uniform?
How many peaks does the histogram have, and in which class(es)
are they located
(must include the correct lower and upper bounds for each class
listed)?
Does the histogram have any gaps between classes? If so, where
are they?
