The College of Dentistry at the University of Florida has made a commitment to develop its entire curriculum around the use of self-paced instructional materials such as videotapes, slide tapes, and syllabi. It is hoped that each student will proceed at a pace commensurate with his or her ability and that the instructional staff will have more free time for personal consultation in student-faculty interaction. One such instructional module was developed and tested on the first 50 students proceeding through the curriculum. The results summarizing the number of hours it took these students to complete the required modular activity is given below. Assume these measurements are representative of all students that eventually complete the self-paced modular activity. Summary Statistics Mean 15.96 Std Dev 8.4996038 Std Err Mean 1.2020255 Upper 95% Mean 18.375561 Lower 95% Mean 13.544439 N 50 The College of Dentistry understands that the students have busy lives. Some may be married with children and have to work to pay for their education. Is there enough evidence that, on average, students can complete the modular activity within a day? Perform a hypothesis test using a significance level of 0.05.
As an IT company, your boss asks you to prepare the computer for a new employee "Julia". List the steps that you will take to accomplish this task.
In a spectrophotometer set at the λmax of a sample the value of P0 (with the solvent) was found to be 85.4 using cuvettes of 2.00 cm path length. The value of P for a solution of the sample having a concentration of 1 × 10^4 M was measured in the same cuvette and was found to be 20.3. Calculate the molar absorptivity of the sample.
