Various literacy groups recommend a reading speed of 167 words per minute (wpm) for grade 5 learners. A grade 5 teacher is convinced that the average reading speed for his class is more than the recommended reading speed. In a sample of 36 grade 5 learners, the average reading speed is 175 wpm with a standard deviation of 22 wpm. You are required to test the teacher's hypothesis that (at a 5% level of significance) his grade 5 class reading speed is more than the recommended reading speed and choose the incorrect statement from the list of options below. A. We do not reject the null hypothesis and conclude that grade 5 average reading speed is more than 167 wpm. B. We do not reject the null hypothesis and conclude that grade 5 average reading speed is not significantly different from 167 wpm. • C. We reject the null hypothesis and conclude that grade 5 average reading speed is more than 167 wpm. D. There is not enough information provided to decide and conclude about the null and alterative hypothesis. E. We reject the null hypothesis and conclude that grade 5 average reading speed is not significantly different from 167 wpm Reset Selection ● Various literacy groups recommend a reading speed of 167 words per minute (wpm) for grade 5 learners.
