Solve the problem.

Suppose you know that the distribution of sample proportions of the residents  of one town over 70 years old in samples of 110 residents  is normal with a mean of 0.12 and a standard deviation of  0.02. You select a sample of 110 residents and find that the proportion of residents  over 70 is 0.08.  The standard score corresponding to this sample proportion is -2. What is the probability that a second sample would be selected with a proportion less than 0.08?
