Problem:
Obtain a random sample size n of at least 30 on a
random variable of your choice. Plot the frequency histogram, and
compute the mean, standard deviation, and skew. Use the relative
frequency histogram to determine the interval probability,
cumulative probability, and exceedence probability of values of
your choice (choose any valuss of your choice) Use the handout, in
photos below, which contains precipitation data for College Station
to guide you.
