Define a class that has one data attribute of type float. The
initializer does not accept an argument, however, it initializes
the data attribute to zero. Include in class the following
methods:
1. func that will accept as two arguments. The first argument a
value of float type and the second argument if string. The function
will perform the following depending on the string argument:
a. if string is '+', the first argument will be added to the...
What type are each of these: discrete, continuous, or
categorical?
and What level are each: interval, ordinal, ratio, nomial?

Give five examples of qualitative data that you could collect
from your coworkers. What would this information tell you about
them and why would it be useful.
The data below represent the ages of drivers and the number of
accidents reported for
each age group in Pennsylvania for a selected year. Use an excel
spreadsheet to
create a scatter plot and calculate the sample
correlation coefficient. At the α = 0.10
level, test for a significant correlation between age and number of
accidents.
