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.

Data: 25 25 26 27 28 30 30 31 32 35 35 38 16) Write a sentence describing the shape of the distribution (skewed or symmetric). 17) How close together are your mean and median? Does this support your thoughts of skewness or symmetry for #16? Use the empircal rule to answer the following: 1) Assume the mean is 29 and the standard deviantion is 2. Draw the curve, identify the mean at the center, count out the standard deviations...
Internet packets can be classified as
video (V) or as generic data ( D). Based
on a lot of observations taken by the Internet
service provider, we have the following
probability model: P[V] = 3/4, P[D] =
1/4. Data packets and video packets occur
independently of one another. The random
variable Kn is the number of video packets
in a collection of n packets.
a) What is E[K100], the expected number
of video packets in a set of 100 packets?...
