Random variable

Goals According to the flow chart above, we need to generate a binary sequence of 0's and 1's, the length of which is 2N bits, that occur with equal probability and are mutually independent for which a ‘rand’ function is used. The data is then passed through a QPSK modulator to produce N complex symbols of {±1 , ±1j}. At the receiver, noise is added to the transmitted signal and the resultant signal is then passed through the QPSK demodulator to produce estimates of the transmitted binary data.…

Alphonse Allais mentions, “Statistics have shown that mortality increases perceptibly in the military during wartime” (Statistics Quotes, 2). The author, Stephen M. Stigler, written the book title “The History of Statistics: The Measurement of Uncertainty before 1900”, expressing the beginnings of statistics between the years 1700 to 1900. Stigler demonstrated how the roles of statistics play in applied sciences of “astronomy, geodesy, experimental psychology, genetics, and sociology” (Stigler…

This work focuses particularly on a Soldier who…

ISE SUMMER PROJECT 2015 Probability, randomness, and chance should be central in any STEM pedagogical model. The concepts of randomness and chance play a very significant role in the essence of all sciences, and especially in the empirical sciences. Randomness is a critical component of biological modeling at many levels in a wide range of systems. The fundamental axioms of the quantum paradigm in physics are, by definition, essentially stochastic. Economics uses the randomness in human thought…

1. What is an exact probability model for the number of automobile accidents over the past year for the 50 medical interns? (Note: The 11 reported accidents include both police-reported and non-police-reported accidents). Answer:- Fixed Proportion = .065 Number of interns involved in accident last year = total number of interns*.065. n = .065*It where n denoted interns in an accident and It denotes the total number of interns. P(n) = ItCn*.065^n*.935^(It-n)......from .binomial probability…

Total profit will increase by __________. Round your answer to the nearest integer and do not include the dollar “$” sign. 1. ------------------------------------------------- Kitty Kennels provides overnight lodging for a variety of pets. An attractive feature is the quality of care the pets receive, including well balanced nutrition. The kennel’s cat food is made by mixing two types of cat food to obtain the “nutritionally balanced cat diet.” The data for the two cat foods are as…

My dependent variable will be their perception of their latest relationship. To measure this, I will be using a Guttmann scale. This will enable me to incorporate both a dichotomous scale and a Likert scale. A dichotomous scale is when a question has two possible responses. A Likert scale is a type of rating scale that measures how someone feels about a certain topic containing degrees of feeling. With multiple Likert questions in a survey Cronbach’s alpha helps measure its reliability.…

information requirements. (a) What process did you use for identifying predictor variables for modelling botnet traffic flows? (b) What additional measures can be taken in terms of information (or data) gathering to further improve the accuracy of the prediction models? (a) I started with a literature survey and read articles to understand the problem and technical terms. To understand the cause-effect relationships, each variable was individually explored. Ricardo and Raihan did a good job in…

taking into account the 7 variables of the question, the degree of reliability is high. However, it was necessary to eliminate the economic uncertainty variable to assure the reliability, because that question presented a higher result than 0.801 which is the Cronbach’s Alpha (See Table…

precise, as the average weight difference is identical to that of the weight difference caused the glucose solution. Low levels of precision can be accounted for by random errors. Random errors are errors caused my unpredictable factors such as wind change or a mistake in the method. In this experiment, there are many possible sources of random errors that may have influenced the results and these may have…
