Systolic blood pressure in healthy adults is normally distributed with mean 112 mmHg and standard deviation 10 mmHg. You take 15 healthy adult patient blood pressure readings and find that the average is 110 mmHg and the standard deviation is 12 mmHg. Compute the standard error. Round to two decimal places (the hundredths place).

Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg) and the standard deviation is 5.6. Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. If a sample of 24 adults is randomly selected, find the probability that the sample mean will be between 117.4 and 120 mm Hg. Assume that the sample is taken from a large population and the correction factor can be ignored.

The following chart defines the ranges for normal blood pressure, high normal blood pressure, and high blood pressure (hypertension). All values are measured in millimeters of mercury (mm Hg). (Source: American Heart Association.) (TABLE NOT COPY) Write an inequality using the variable $p$ that represents each condition. Normal systolic blood pressure.
