Xr12-98 A professor of business statistics recently adopted a new textbook. At the completion of the course, 100 randomly selected students were asked to assess the book. The responses are as follows.

Excellent (1), Good (2), Adequate (3), Poor (4)

The results are stored using the codes in parentheses.

Do the data allow us to conclude at the 10% significance level that more than 50% of all business students would rate the book as excellent?
