Question 439309: Please help! This is the last question of the last week of this class. Thank you for your help. John Isaac, Inc., a designer and installer of industrial signs, employs 60 people. The company recorded the type of the most recent visit to a doctor by each employee. A national assessment conducted in 2008 found that 53 percent of all physician visits were to primary care physicians, 19 percent to medical specialists, 17 percent to surgical specialists, and 11 percent to emergency departments. Test at the .01 significance level if Isaac employees differ significantly from the survey distribution.

You listed the population proportions but not the John Isaac numbers
for its 60 employees. So no comparison can be made.
