“More than half of California’s doctors say they are so frustrated with managed care they will quit, retire early, or leave the state within three years.” This conclusion from an article titled “Doctors Feeling Pessimistic, Study Finds” (*San Luis Obispo Tribune,* July 15, 2001) was based on a mail survey conducted by the California Medical Association. Surveys were mailed to 19,000 California doctors, and 2000 completed surveys were returned. Describe any concerns you have regarding the conclusion drawn.

To determine

Comment on the appropriateness of the conclusion given by medical association.

A state C medical association sends survey questionnaire by e-mails to 19,000 doctors of state C. Among 19,000 doctors, 2,000 doctors completed the survey questionnaire. Based on their responses, state C medical association concluded that “More than half of the state C doctors are frustrated with managed care and willing to quit, retire early, or leave the state within three years”.

State C medical association sends questionnaire to 19,000 doctors of state C and records their responses, without attempting to manipulate or influence the responses.

Hence, this is an observational study. As the data are collected by asking questions, it is a survey.

Here, among 19,000 doctors, 2,000 doctors completed the survey questionnaire.

The probability of response is obtained as given below:

The proportions of doctors responded to the survey is very low (0
