Question

6.72 Who is the author? Statistics can help decide the authorship of Iterary works. Sonnets bya certain Elizabethan poet are known to contain an average of μ 8.9 new words (words not used in the poet's other works). The standard deviation of the number of new words is σ-25. Now a manuscript with six new sonnets has come to light, and scholars are debating whether it is the poet's work. The new sonnets contain an average of x10.2 words not used in the poet's known works. We expect poems by another author to contain more new words, so to see if we have evidence that the new sonnets are not by our poet we test H0: μ 8.9 Ha: μ > 8.9 Give the z test statistic and its P-value. What do you conclude about the authorship of the new poems?
