What do the results mean?

7.59 A U.S. database contains patients with colon tumors. The colon tumor in each patient may or may not be cancerous. A random sample 100 patients with colon tumors was clinically tested (biopsy) to be classified as malignant or nonmalignant. The results reveal that 66% of the colon tumors were malignant, contrary to the belief that the true proportion was about 50%. a) Use the data of the experiment and obtain 99% confidence limits on the true proportion of malignant colon tumors.
