Question 1183989
point estimate mss 24/49=0.4898
z=(0.4898-0.60)/sqrt(0.6*0.4/49)
=-0.1102/0.07
=-1.57
that probability that z is <= -1.574=0.0577
(remember this is a continuous function, so the probability has to be over an interval, not a single value on the curve, where the probability would be 0.)
