Using the above data, do the following:
1. Use data set 1
a. Construct a frequency distribution and percents.
b. Find the mode.
c. Construct a frequency histogram.
d. What is the probability of selecting someone whose favorite color is red?
Part 2
a. Construct a frequency distribution and a cumulative frequencydistributionwithout grouping the data.
b. Find the mean, median, mode, midrange and range.
c. Find the variance and the standard deviation.
d. Find the fivenumber summaryand construct a b oxplot.
e. What is the probability of selectine a clas s with 20 students?
Part 3:
a. Using 6 classes and a class width of 5, constnct a frequency distributionand a cumulative frequency distribution (firstclass: 7 11).
b. Find the modal class.
c. Using the frequency distribution from part a: Find the mean, variance and standexcldeviation.
d. Usingthe frequency distribution from parta: What is the probability of a randomly selected herb to have a height of at least 17 inches?
e. Using the frequency distribution constructed in parta: What is the probability of a randomly selected herb to have a height more than 26 inches?
