The table below shows the probability distribution of job satisfaction scores (1 - 4) for a group of senior executives. A score of 1 indicates a strong dissatisfaction with their jobs; a score of 4 indicates a strong satisfaction with their jobs.Note that you must complete both parts a. and b. to receive any marks for the remaining parts of this question.a. Complete the missing value in the following table. Round to at least FIVE decimals if necessary. Job Satisfaction Score Probability of Score 1 0.2 2 3 0.27 4 0.26 b. What is the expected job satisfaction score for this group of senior executives?Answer: Do NOT round your answer!c. What is the standard deviation of the job satisfaction score for this group of senior executives?Answer: Round to at least FIVE decimals if necessaryd. Suppose a senior executive expects to earn an additional 4350 dollars per year for each job satisfaction score point. The executive also will receive a fixed 250 dollar yearly raise and…
