Random variable 1 -
The random variable should be modeled with a Binomial distribution because, it has the below properties.
The parameter values of the distribution is n = 10. P = 0.02
The probability mass function is,
P(X = x) = nCx * 0.02x * (1 - 0.02)10-x = nCx * 0.02x * 0.9810-x
Random variable 2 -
The random variable should be modeled with a Poisson distribution because, it has the below properties.
The parameter of the distribution is = 0.8.
The probability mass function is,
P(X = x) = (e-0.8) (0.8x) / x!

Part 3. (13 points) Simulation of Gamma Random Variables Background: When we use the probability density function to find probabilities for a random variable, we are using the density function as a model. This is a smooth curve, based on the shape of observed outcomes for the random variable. The observed distribution will be rough and may not follow the model exactly. The...

Problem 2. Calculate Grades (35 points) Arrays can be used for any data type, such as int and char. But they can also be used for complex data types like structs. Structs can be simple, containing simple data types, but they can also contain more complex data types, such as another struct. So you could have a struct inside of a struct. This problem deals with...

2. Model : We will replace our data with a probability mass function. In other words assume we know that of all the world's beers 70% are low alcohol, 20% are medium alcohol and 10% are high alcohol. We also assume all low alcohol beers are 5.13% ABV, medium are 6.85% ABV and high is 10.20% ABV. Let X be a random variable representing the ABV of a randomly selected beer. a. (4pts)...

Help with this page is greatly appreciated. I dont understand
how to show a full diagram. Thanks in advance :)
The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...
