1. Given the data set: 40, 40, 35, 48, 38, 40, 36, 50, 32, 36,
40, 35, 30, 24, 40, 36, 40, 39, 33, 40, 32, 38, construct an
appropriate frequency distribution table and draw a frequency
histogram, frequency polygon, and ogive. number of classes =5
2. Use the following table to find the following
probabilities:

a) Use statistical software to construct a relative frequency
histogram. Use 32 as the lowest class limit and a class width of 2.
Plot and label the statistics x̄ (x-bar), x̄+1, x̄+2, x̄+3. Draw a
normal density curve on the relative frequency histogram. Comment
on the shape of the distribution.
b) Do you think the normal density curve accurately describes
the heights of five year...
