Assignment:
In tests of a speed-reading course, it is found that 10 subjects increased their reading speed by an average of 200 words per minute, with a standard deviation of 75 words. At the 0.10 level, does this sample information suggest that the course is really effective in improving students’ reading speed? Using the appropriate statistical table, what is the approximate p-value for this test?
Provide complete and step by step solution for the question and show calculations and use formulas.
