Statistics Assignment - Speech or Presentation ExampleThe probability of winning the lottery is then around nine in a billion. It should be noted that the resulting equation actually simplifies to a multiplication rule. However, the binomial distribution may be used to model more complex lottery options.In the construction of a 5-digit number, the order in which is numbers are drawn is clearly important. Also, since repetition of digits is not allowed, a single digit chosen is removed from the pool of possible succeeding digits. These conditions indicate that the total number of digits peck simply be taken using a permutation.The given flurry can only be classified as a probability distribution if its individual probabilities are betwixt zero and one and the total probability is cope with to one. In the given table, the probability at X = 2 is greater than one. Since no negative probabilities are present, the total probability is also greater than one. As both requirements are n ot met, the table cannot be a probability distribution.The sample data is relatively sparse (n To determine whether a relationship exists between the two variables, the given data may be fitted onto a function. The simplest approach is to use a linear model for approximating the relation. To aid in this, a tug representation may be constructed. It should be noted that the independent variable based on the description is the cost of the product.An sour frequency distribution is assumed in this case which allows the use of the Goodness of Fit test. The computations for the chi square statistic can then be determined as shown in the following tableData is a very important
