Binomial distribution

In Excel, the function =NORMINV(RAND(),100,5) will return a normally distributed random number with a standard deviation of 100 and mean of 5. Answer: FALSE Page Ref: 415 Topic: Role of Computers in Simulation Difficulty: Moderate 27) A binomial distribution can yield only two outcomes. Answer: TRUE Page Ref: 416 Topic: Role of Computers in Simulation Difficulty: Moderate 28) Monte Carlo simulation and operational gaming are the only two categories of simulation. Answer: FALSE Page Ref:…

1. Compute the mean and variance of the following discrete probability distribution. x P(x) 2 .50 8 .30 10 .20 x P(x) xP(x) x2P(x) 2 0.50 1.00 2.00 8 0.30 2.40 19.20 10 0.20 2.00 20.00 Total 1.00 5.40 41.20 Mean = 5.40 Variance = 41.20 - 5.40^2 = 12.04 Answer: Mean is 5.4 and variance is 12.04 2. The Computer Systems Department has eight faculty, six of whom are tenured. Dr. Vonder, the chair, wants to establish a committee of three department faculty members to review…

the case of a pandemic the calculations will tell how quickly the health event is spreading and the probability of it spreading. Concept 10.0 Uses of epidemiology in public health This concept is in Module 11 Epidemiology is the study of the distribution and determinants of health and disease-related states in populations, and the application of this study to control health problems. Epidemiology is thus very useful to the field of public health in the control and prevention of catastrophic…

is according to Poisson distribution. It is one of the most widely used and oldest traffic models. In this model the length of each packet is based on exponential distribution and the number of simultaneously ongoing packets is according to Erlang distribution [16]. The Poisson process is characterized as a renewal process. In a Poisson process the inter-arrival times are exponentially distributed with a rate parameter λ: P{An ≤ t} = 1 – exp(-λt). The Poisson distribution is appropriate if the…

freeway crashes during winter periods in the State of Michigan. Two principal Negative Binomial regression models were established to assess these effects. Explanatory variables for Model 1 included AADT, segment length, horizontal curvature, and snowfall. Explanatory variables for Model 2 included all three initial variables from Model 1 and three categorical snowfall intervals based on its quartile distribution. Crash categories considered in the analysis included total winter, truck/bus,…

approximately = (1 ): Formally, let random variable X be the number of girls in a family in the second village. Then under conventional assumptions, X has a geometric distribution (a special negative binomial distribution with r = 0). The p.d.f. of X is x f (x) = (1 ) and the expectation of X is E (X)…

Average annual rates of specific events comprising disease-free survival were computed and compared by use of exact binomial probabilities. The Cox proportional hazards model was used to examine prognostic covariates and to test for interactions between treatment and the covariates (11). Age at diagnosis, clinical tumor size, ER status, and PgR status were evaluated for…

the number from the fossil record. The random sample from current data and the data from the fossil record were coupled and used to model the suitability of thermal conditions for the growth of coral reefs. A generalized linear models with binomial distribution was used to gain a curve. Then to evaluate the model the team ran runs with a split of 70% of the data used to model and the remaining 30% used to verify the predictions; this was able to prove the information…

per game and 3-point percentage. Since LeBron James and Michael Jordan start their professional NBA almost at the same age, so I decided to compare the first nine years. The methods used to calculate the statistics were linear regression and binomial distribution. Linear Regression was used determine the relationship between LeBron James production and his salary. I used statistics to determine the probability of LeBron James making 8 field goals in a row. Also, I designed a C program to…

sampling method was also used to collect data from the various health records such as referral letters and doctors recommendations. The collected data was analyzed using various tests. First 95% confidence was calculated using Clopper-Pearson binomial distributions assumptions. Binary logistic regression with the help of step-wise approach was used to identify the risk factors that lead to inappropriate prescribing as a result of hospitalization. The benefits that go along with correlation and…
