Average salary of the sample is:

1. series avgsal =@mean(salary)

2. show avgsal

3. avgsal = 865.86

Therefore the average salary of the sample is $865,860.

Average tenure of the sample is:

1. Depends if we are talking about company tenure, or tenure as CEO.

2. To find average tenure with the company:

a. series avgcomten =@mean(comten)

b. show avgcomten

c. avgcomten = 22.50

3. To find average tenure as CEO:

a. series avgceoten =@mean(ceoten)

b. show avgceoten

c. avgceoten = 7.95

Therefore the average tenure with the company and as CEO is respectively 22.50 and 7.95 years.

2.

The number of CEOs that in their first year of CEO is:

a. smpl if ceoten=0

b. scalar count = @obssmpl

c. show count = 5

The longest tenure as CEO is:

a. series maxceoten = @max(ceoten)

b. show maxceoten

c. maxceoten = 37

3.
