A student decided to enroll in a reading course that allegedly increases reading speed & comprehension. Prior to enrolling in the class, the student reads 198 words per minute (wpm). The following data represent the wpm for 10 different passages read after the course. 206, 210, 217, 197, 197, 212, 199, 227, 210, 209 Because the sample size is small some work was previously done to verify that the data is normally distributed & has no outliers. Determine if the course was effective using an α=0.10 level of significance. 1A) State the appropriate hypothesis to test & confirm any necessary checks to perform the testing. 1B) Calculate the mean and the standard deviation of the data. 1C) Calculate the appropriate Test Statistic.
