Question:

The Journal of Professional Issues in Engineering Education and Practice (Apr. 2005) reported on the results of a 2005 survey of courses offered at undergraduate engineering programs. Of the 90 engineering programs that participated in the 2005 survey, 78 covered fluid mechanics. In a survey taken 20 years earlier (Engineering Education, Apr. 1986), 76 of the 100 undergraduate engineering programs covered fluid mechanics. Conduct a test to determine whether the fraction of undergraduate engineering programs covering fluid mechanics increased from 1986 to 2005. Use. a = .01

An Engineering firm advertises a job offer for recent graduates of Mechanical Engineering through three media: El Heraldo, El Portal de Uninorte graduates and through social networks. It is known that each of these media is consulted by recent graduates of Mechanical Engineering with a probability of 0.1, 0.4 and 0.5 respectively. Likewise, it is known that a recent graduate of Mechanical Engineering applies to a job offer having consulted the Heraldo with a probability of 0.002; the portal of graduates of Uninorte with probability 0.001 and social networks with 0.005. Assume that a recent graduate of Mechanical Engineering consults only one medium.

a) What is the probability that it will be applied to a job offer?

b) If the Engineering firm receives an application to the job offer, what is the probability that the applicant recently graduated from Mechanical Engineering has consulted the Herald?

Which data would be suitable for a pie chart?

a.) Whirlpool Corporation's sales revenue for the last five years.

b.) Oxnard University student category (undergraduate, masters, doctoral).

c.) Average SAT scores for entering freshmen at major U.S. universities.

d.) U.S. toy imports from China over the past decade.
