Suppose that the distribution of scores of 1,000 students who take a standardized intelligence test is a normal distribution. Also suppose that the distribution's mean is 450 and its standard deviation is 25. a) How many scores do we expect to fall between 400 and 500? b) How many scores do we expect to fall below 400? a) It is expected that score(s) fall between 400 and 500. (Round to the nearest whole number as needed.)
