Overall proportion of satisfied patients from a prior year

Reference no: EM131384547

Consider Table on the summary of patient satisfaction ratings. The percentages in each rating category are based on a response from a total of 200 patients from a prior year. For the item waiting time prior to being seen by a physician, consider the combined proportion of patients who are satisfied, that is, includes those in the category of very satisfied or satisfied.

Suppose that, based on a survey during the current year, out of a total of 400 patients, 85% of them expressed a rating of very satisfied or satisfied.

Can we conclude that there has been an increase in the overall proportion of satisfied patients from a prior year to the current year? Use a level of significance of 5%.

Table - Patient Satisfaction Data on Timeliness of Operations

1. Waiting time at registration	10	40	20	20	10
2. Time to occupy bed	10	30	30	20	10
3. Waiting time prior to being seen by a physician	10	5	10	40	35
4. Timeliness of nurse visits	30	20	20	20	10
