The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 122 and standard deviation of 24. a. Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. Around what percentage of adults in the USA have stage 2 high blood pressure? Give your answer rounded to two decimal places. % b. Stage 1 high BP is specified as systolic BP between 140 and 160. What percentage of adults in the US qualify for stage 1? Round to 2 decimal places. % c. Your doctor tells you you are in the 45 th percentile for blood pressure among US adults. What is your systolic BP? Round to 2 decimal places. mmHg Interpret the 45 th percentile, what does this mean? d. What two values divide this normal curve into a middle 91%, in other words, what two values represent the middle 91% of blood pressures? Put the lower number FIRST! mmHg and e. How many standard deviations away from the mean would a blood pressure of 145 be? f. Would this be considered unusual? Very Unusual
