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, 68 covered fluid mechanics. In a survey taken 20 years earlier (Engineering Education, Apr. 1986), 66 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 α = .01.

Please follow these steps:

1. State the null and alternate hypothesis.

2. significance level used.

3. Test statistic.

4. p-value.

5. Decision.

6. Conclusion.
