a. To determine Draw the probability distribution. Explanation Calculation: The probability distribution of a random variable x is given as follows: p ( x ) = 3 x e − 3 x ! , x = 0 , 1 , 2 , ... Poisson distribution: A random variable x is said to have a Poisson distribution with mean λ if the probability distribution of x is as follows: p ( x ) = λ x e − λ x ! , x = 0 , 1 , 2 , ... On comparing the given probability distribution with the mass function of Poisson distribution, it can be observed that the value of λ is 3. The mean is 3. The probability distribution of x is obtained as follows: Software procedure: Step-by-step procedure to obtain the probability density function using MINITAB software: Choose Calc > Probability Distributions > Poisson b. To determine Obtain the mean and standard deviation of x .

Question 2: When John started his first job, his first end-of-year salary was $82,500. In the following years, he received salary raises as shown in the following table. Fill the Table: Fill the following table showing his end-of-year salary for each year. I have already provided the end-of-year salaries for the first three years. Calculate the end-of-year salaries for the remaining years using Excel. (If you Excel answer for the top 3 cells is not the same as the one in the following table, your formula / approach is incorrect) (2 points) Geometric Mean of Salary Raises: Calculate the geometric mean of the salary raises using the percentage figures provided in the second column named “% Raise”. (The geometric mean for this calculation should be nearly identical to the arithmetic mean. If your answer deviates significantly from the mean, it's likely incorrect. 2 points) Hint for the first part of question 2: To assist you with filling out the table in the first part of the question,…
