# Mean

Teachers will not use a book in Grade 5 unless the reading level for a typical page can be shown to be above grade level 4.000. Grade level measurements are summarized: n=10, x bar=5.108, s=1.412 Use a 0.05 significance level to test claim that the mean is greater than 4.000. Assume simple random sample and that the pop of means is normally distributed.
