SUMMARY

The moment generating function (mgf) for the random variate X is defined as Mx(t) = 0.8(e^t + 0.2)^11. To find P(X > 0) and E[X^2], one must first clarify the correct formulation of the mgf. The discussion emphasizes the importance of understanding the problem before seeking assistance, as participants are encouraged to demonstrate their current knowledge and challenges faced.

PREREQUISITES
  • Understanding of moment generating functions (mgf)
  • Basic knowledge of probability theory
  • Familiarity with expected value calculations
  • Proficiency in algebraic manipulation
NEXT STEPS
  • Study the properties of moment generating functions (mgf)
  • Learn how to calculate probabilities using mgf
  • Explore methods for finding expected values, particularly E[X^2]
  • Review examples of random variates and their mgfs
USEFUL FOR

Students in statistics or probability courses, educators teaching probability theory, and anyone interested in understanding moment generating functions and their applications in statistical analysis.

Do you mean "mgf" ("moment generating function") and should that be
[itex](0.8e^t+ 0.2)^11[/itex] or [itex]0.8(e^t+ 0.2)^11[/itex]?

i) Find the P(x>0)
ii) Find E[x2]
You seem to have the wrong idea about this board. We don't do your homework for you. Show us what you know about this problem, what you have tried, and where you are stuck.
 
hey , i have the same problem too, i don't know how to start at this. please help. just tell how to proceed.
