A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm. 
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

The probability distribution of the random variable X represents the number of hits a baseball player obtained in a game for the 2012 baseball season.

xP(x)00.16710.328920.280130.14940.038250.0368
The probability distribution was used along with statistical software to simulate 25 repetitions of the experiment (25 games). The number of hits was recorded. Approximate the mean and standard deviation of the random variable X based on the simulation. The simulation was repeated by performing 50 repetitions of the experiment. Approximate the mean and standard deviation of the random variable. Compare your results to the theoretical mean and standard deviation. What property is being illustrated?
a) Compute the theoretical mean of the random variable X for the given probability distribution.
μ=?
b) Compute the theoretical standard deviation of the random variable X for the given probability distribution.
σ=?
c) Approximate the mean of the random variable X based on the simulation for 25 games.
X=?
d) Approximate the standard deviation of the random variable X based on the simulation for 25 games.
S=?

The geyser Old Faithful in Yellowstone National Park alternates periods of eruption, which typically last from 1.5 to 4 minutes, with periods of dormancy, which are considerably longer. The following table presents the durations, in minutes,30 of dormancy periods that occurred during a recent year.Construct a frequency distribution using a class width of 7, and using 55 as the lower class limit for the first class.
