Question

Two drugs were tested to see whether they helped women with breast cancer. Of 1060​ women, about half were randomly assigned to drug A and the other half were assigned to drug B. After 77​ months, 473 out of​ 539, and 426 out of 521 women assigned to drugs A and​ B, respectively, were alive. (a) The survival rate for drug A is ______ %. (b) The survival rate for drug B is ______ %.

Answer 1

Answer:

(a) The survival rate for drug A is 87,75%.

(b) The survival rate for drug B is 81,76%.

Step-by-step explanation:

To get the survival rate of each drug you have to divide the number of women alive between the total number of women that use the drug.  

For drug A= women alive that use drug A/ total number of women that use the drug A= 473/539

For drug A=0,8775= 87,75%

For drug B= women alive that use drug B/ total number of women that use the drug B

For drug B== 426/521= 0,8176 = 81,76%
