A SRS of 25 men ages 65 and older<br>is taken.<br>A. Calculate the probability that proportion of men ages 65 and older who<br>have been diagnosed with some form of cancer is more than 0.30.<br>a) 0.2033<br>b) 0.7967<br>c) 0.2236<br>d) This can't be done because n is not greater than 30 and we are not told<br>that the variable is normally distributed.<br>B.
