Michael Sullivan, son of your textbook author, decided to enroll in a reading course that allegedly increases reading speed and comprehension. Prior to enrolling in class, Michael read 198 words per minute (wpm). The following data represent the words per minute read for 10 different passages read after the course:

206,217,197,199,210,210,197,212,227,209.

Use p-values method to test the hypothesis that the class was effective. Hint: if it was effective, then the average speed at which these passages were read has increased compared to 198. Assume that reading speed is normally distributed and sample does not contain any outliers. Use α=0.10 level of significance and show the work below:

The null hypothesis is:_____________________
