A survey of 300 hospital workers is taken. The question asked is "Do you think that staffing is adequate at your hospital, yes or no?" Perform the Chi-square test to determine if the frequency of no responses is statistically larger than the frequency of yes responses. The following responses were received: yes - 120, no - 180.

Expert Solution

We have used Chi-square goodness of fit to test the hypothesis.

Thus, at 0.05 significance level, it can be concluded that the frequency of no responses differ from the frequecny of yes responses. In other words, at 0.05 significance level, the frequency of no responses is statistically larger than the frequency of yes responses
