2.16. Compare the Poisson approximation to the actual binomial proba-
,
bility PX =( 4) , using n = 9 and p = 0.1 0.2 … 0.9.
,
,
2.17. Using the function normspec, find the probability that the random
variable defined in Example 2.5 assumes a value that is less than 3.
What is the probability that the same random variable assumes a
value that is greater than 5? Find these probabilities again using the
function normcdf.
2.18. Find the probability for the Weibull random variable of Example 2.8
using the MATLAB Statistics Toolbox function weibcdf or the Com-
putational Statistics Toolbox function csweibc.
2.19. The MATLAB Statistics Toolbox has a GUI demo called disttool.
First view the help file on disttool. Then run the demo. Examine
the probability density (mass) and cumulative distribution functions
for the distributions discussed in the chapter.
