A consensus forecast is the average of a large number of individual analysts' forecasts. Suppose the individual forecasts for a particular interest rate are normally distributed with a mean of 6 percent and a standard deviation of 1.7 percent. A single analyst is randomly selected. Find the probability that his/her forecast is (a) At least 3.9 percent. (Round the z value to 2 decimal places. Round your answer to 4 decimal places.) P (b) At most 7 percent. (Round the z value to 2 decimal places. Round your answer to 4 decimal places.) P (c) Between 3.9 percent and 7 percent. (Round the z value to 2 decimal places. Round your answer to 4 decimal places.)
