Assume that a randomly selected subject is given a bone density test and that scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability of the given bone density scores deviating from the mean as follows: Between -2.5 and -0.75 Greater than .78 For bone density scores that are normally distributed with a mean of 0 and a standard deviation of 1, find the percentage of scores that are significantly high, or at least 3 standard deviations above the mean significantly low, or at least 3 standard deviations below the mean not significantly high or low, or within -3 and 3 standard deviations from the mean
