To study the effectiveness of a speed-reading course, eighteen people participated in a study. Prior to taking the course, the reading speed (in words per minute) was recorded for each participant. The eighteen participants then took the speed-reading course and their reading speed was again measured after the course. The data appear in the Reading worksheet of the Two Population Hypothesis Tests HW data workbook on Moodle. a) What are the null and alternative hypotheses to test if reading speed...

            It is well known that increasing room illumination up to some level increases reading comprehension.  A random sample of 10 sixth-grade students read standardized passages under two levels of ambient room illumination: 5 foot candles and 15 foot candles (more candles, more light). The order in which the conditions were presented was randomized and reading sessions were separated by an interval of 2 hours. A higher score reflects better reading comprehension. Test this well-known belief.

7. Philip wants to take a speed-reading course, but his wife thinks that it is a waste of time. To convince her that the course will really change the way that he reads, Philip decides to conduct an informal study. He pols seven people, asking them to tell the number of pages they were able to read in an hour before and then after they took the course. The results he obtained are found in the following table. Construct and...
