For a data set of diastolic blood pressure measurements of males, the lowest measurement is 39.5 mmHg. The 153 males have a mean of x = 71.26 mmHg and a standard deviation of s = 11.99 mmHg. a. What is the difference between the lowest diastolic blood pressure and the mean of the diastolic blood pressures? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the lowest diastolic blood pressure to a z score. d. If blood pressures that convert to z scores between -2 and 2 are considered to be neither significantly low nor significantly high, is the lowest blood pressure significantly low, significantly high, or neither? a. The difference is mmHg. (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z = (Round to two decimal places as needed.) d. The lowest blood pressure is
