d. What is the probability a middle manager is very satisfied?

Answer:

(c)0.83

(d)0.28

Explanation:

The percent frequency distributions of job satisfaction scores os give below:

`\left|\begin{array}c$Job Satisfaction Score&$IS Senior Executives(\%)&$IS Middle Managers(\%)\\1&5&4\\2&9&10\\3&3&12\\4&42&46\\5&41&28\end{array}\right|`

(a)Probability distribution for the job satisfaction score of a senior executive.

`\left|\begin{array}c$Job Satisfaction Score&$Relative Frequency (f_1(x))\\------&------\\1&0.05\\2&0.09\\3&0.03\\4&0.42\\5&0.41\end{array}\right|`

(b)Probability distribution for the job satisfaction score of a middle manager.

`\left|\begin{array}c$Job Satisfaction Score&$Relative Frequency (f_2(x))\\1&0.04\\2&0.10\\3&0.12\\4&0.46\\5&0.28\end{array}\right|`

(c)Probability a senior executive will report a job satisfaction score of 4 or 5

P(a senior executive will report a job satisfaction score of 4 or 5)

`=f_1(4)+f_1(5)\\=0.42+0.41\\=0.83`

(d)Probability a middle manager is very satisfied

The probability a middle manager is very satisfied

`=f_2(5)\\=0.28`
