A doctor is studying a new disease and it's possible that the five year survival rate for some patients can be improved if the standard treatment is lengthened from one year to one and a half years. 50 patients were treated for 1.5 years and 15 did not survive for five years as predicted. If p is the survival rate for individuals treated for the disease over 1.5 years. Can you construct a 99% confidence interval for p and find the right sample size that the doctor would need so the margin of error for the 99% CI for p is less than 0.1?
