the personnel department of Ztel, a large communications company,is reconsidering its hiring policy. Each applicant for a job must take a standard exam,
and the hire or no-hire decisions depends at least in part on the result of the exam. The scores of all applicants have been examined closely.
Theyare approximately normally dostributed with mean 525 and standard deviation 55
The current hiring policy occurs in two phases.The first phase separates all applicants into three categories: automatic accepts, automatic rejectand maybes.
The automatic accepts are those whose test scores are 600 or above. The automatic rejects are those whose test scores are 425 or below.
all other applicants (the maybes) are passed on to a second phase where their previous job experince,special talents, and other factors are used as hiring criteria
The personnel manager at ZTEL wants to calculate the percentage of applicants who are automatic accepts or rejects,given the current standards.
