Discuss the utility of statistics as a managerial tool Also describe its limitations?
The limitation of any statistical application is the fact that it always depends on some sampling. If this sampling is incomplete, or not representative of your actual base (say customers), your data may not yield accurate conclusions. Additionally, since it depends on sampling, your measurement is only applicable to a base that fits the profile of your sampling. For instance, if you took your sampling from Caucasian males over age 35, and it turns out your customer base has a large number of African, American females under 23, your conclusions based on the statistics could be imperfect.
What is linear snowball sampling?
This is a non-random sampling technique where the initial respondents to a survey recruit others for a survey. Linear snowball sampling is when the first responent recruits one more person for the survey, who in turn recruits one more person for the survey. Number of people surveyed will increase in a linear manner. The related links provide good discussion of this form of surveying. It is a non-representative sample, but it is an effective means of surveying people with common traits who might otherwise be difficult to find. For example, I want a statistical profile of people that are "hackers" so every hacker I find, I would ask if I could interview his "fellow hackers." See related links.

Manipulation of the predictive index test?
The Predictive Index is not a test with a right or wrong answer. It is a survey of behaviors that results in a profile the describes the person. Companies often know what profile they are looking for in hiring or promotion and use it to compare candidates. The Predictive Index asks you to describe yourself. While it would be easy to answer the Predictive Index in a way that does not describe you (you could randomly answer it, for example), it would be very unlikely that you could answer it in a way that would artificially generate the hiring manager's desired pattern. Since studies show that those who do not match the desired pattern do poorly and tend to be less happy in the job, there is little reason to try to manipulate it. The bottom line is to take it honestly and, if you are right for the job, you'll probably get a shot at it.
