# Normal distribution of Information Systems Degree

Problem 3

Jim is considering pursuing an MS in Information Systems degree. He has applied to two different universities. The acceptance rate for applicants with similar qualifications is 20% for University X and 45% for University Y. What is the probability that Jim will be accepted at one and only one university?

Problem 5

Two Psychology majors, in 2 different sections of Clinical Psychology, were comparing test scores. The following gives the students' scores, class mean, and standard deviation for each section:

.............................Section 1 .......Section 2

Score .........................84 ..................75

Mean ..........................75 ..................60

Standard deviation........7 ...................8

What is the z-score of the student from section 1 and what is the probability that a student in section 1 will score higher than 84?

Problem 6

A loaf of bread is normally distributed with a mean of 22 oz and a standard deviation of 0.5 oz. What is the probability that a loaf is between 20.75 and 23.25 oz?

Problem 7

A study of a company's practice regarding the payment of invoices revealed that on the average an invoice was paid 20 days after it was received. The standard deviation equaled 5 days. Assuming that the distribution is normal, what percent of the invoices is paid within 15 days of receipt?
