Military patients entering the Veterans Hospital in Anchorage have complained that it takes sixty minutes to fill out the required forms for admittance. As a result of all the complaints, the forms and procedures have been revised. A recent analysis of a random sample of nine incoming patients reveals that the mean time to fill out forms is now fifty minutes with a standard deviation of five minutes. Is there sufficient evidence at a five percent significance level to show that the system is an improvement? Assume the population standard deviation is unknown. Use the “t” procedure.
2. Dr. Thomas Brady gave a Principles of Internal Medicine examination and he assumed the results to be normally distributed with a mean of 59 and a standard deviation of 8. He wants to assign an “A” to the top five percent. What is the starting score for an “A”?
In your own words please comment on the following post about polygons:
Polygons are used everywhere in society. The term polygon refers to a closed figure in a plane. Polygons are used in architecture and construction. It is important to know how to classify polygons because polygons are given special names according to their number of sides. For example, a triangle has three sides, a quadrilateral has four sides, where as an octagon has 8 sides. For example when we see a stop sign we do not say hey that is a polygon, we would refer to the stop sign as a hexagon. Another traffic example would be a yield sign which is a triangle. If an architect described a room as being a polygon that contained 3 sides then an individual would be able to take measurements that would allow them to accurately find the perimeter or area of the room. An individual who chooses a career in architecture or construction would themselves using math and measurements frequently. Most architects use shapes to create designs and they must know what type of shape or polygon they are using to get correct and accurate measurements for the rest of their job.
