A Method Currently Used by Doctors to Screen Women for Possible

Essay

A method currently used by doctors to screen women for possible breast cancer fails to
detect cancer in 20% of women who actually have the disease. A new method has been
developed that researchers hope will be able to detect cancer more accurately. A random
sample of 90 women known to have breast cancer were screened using the new method.
Of these, the new method failed to detect cancer in eight. Specify the null and alternative
hypotheses that the researchers wish to test.
