  1. Relying on this data find:
    • the median
    • the lower and upper quartiles
    • the 90thpercentile
    • the interquartile range
    • the mean
    • the standard deviation
  2. Discuss which approach (the mean and standard deviation or the median and interquartile range) better reflects the central tendency and variation for the given data.

A special diet is intended to reduce systolic blood pressure among patients diagnosed with stage 2 hypertension. If the diet is effective, the target is to have the average systolic blood pressure of this group be below 150. After six months on the diet, an SRS of 28 patients had an average systolic blood pressure of ?¯=143 with standard deviation ?=21 . Is this sufficient evidence that the diet is effective in meeting the target? Assume the distribution of the...

The systolic blood pressure of 16 students was measured before a test. The blood pressure from this sample averaged 165, with a standard deviation of 40. a) Compute the approximate 95% confidence interval for mean systolic blood pressure, and make a sketch illustrating these confidence intervals b) If a mean blood pressure above 130 is considered “stressed”, what do your calculations show regarding the probability that the observed mean is above the “stressed” level.

A patient visits her doctor with concerns about her blood pressure. If the systolic blood pressure exceeds 150, the patient is considered to have high blood pressure and medication may be prescribed. The problem is that there is a considerable variation in a patient’s systolic blood pressure readings during a given day. A. If a patient’s systolic readings during a given day have a normal distribution with a mean of 155 and a standard deviation of 20, what is the...

Research Scenario Hypertension is defined as a systolic blood pressure (SBP) of 140 mmHg or more, or a diastolic blood pressure (DBP) of 90 mmHg or more. Diastolic blood pressure (DBP) measurements from the general population form a normal distribution with m = 82 mmHg and s = 10 mmHg. Epidemiological studies have shown that obesity increases the risk of hypertension (high DBP). Using data from a cohort study, a researcher obtained a sample of n = 144 obese persons...

In a group of patients over 30 you find the following: μ = 9.3 mg/dL, and σ = 2.35 mg/dL. a) Give the blood calcium values for the middle 50% of patients. (Hint/comment: if you want the middle 50%, how many percent go in each tail?) b) Give the blood calcium values for the middle 70% of patients. c) Give the 85th percentile. d) Are you surprised by the answers to (b)...
