Question: In a certain county, it has been historically accepted that 52 percent of the patients who go to hospital emergency rooms are in stable condition,

In a certain county, it has been historically accepted that 52 percent of the patients who go to hospital emergency rooms are in stable condition, 32 percent are in serious condition, and 16 percent are in critical condition. However, a particular county hospital feels that its percentages are different. To prove its claim, the hospital has randomly selected a sample of 300 patients who have visited its emergency room in the past 6 months. The numbers falling in each grouping are as follows: 148 patients are stable, 92 are in serious condition and 60 are in critical condition. Do these data prove the claim of the hospital? Explain carefully what the null hypothesis is, and use the 5 percent level of significance.
