Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mmHg) 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. Part 1 of 3 If an individual is selected, find the probability that the individual's pressure will be between 120 and 122.6 mmHg. P(120 < X < 122.6) = 0.1772 Part: 1 / 3 Part 2 of 3 If a sample of 29 adults is randomly selected, find the probability that the sample mean will be between 120 and 122.6 mmHg. Assume that the sample is taken from a large population and the correction factor can be ignored. P(120 < X < 122.6) = X

The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 5.1 mm. Round values to 4 decimal places when possible. The mean of this distribution is . The standard deviation is . The probability that the round off error for a jumper's distance is exactly 4.3 is P(x=4.3)=P(x=4.3)= . The probability that the round off error for the distance that a long jumper has jumped is between 1.5 and 2.5 mm is P(1.5<x<2.5)=P(1.5<x<2.5)= . The probability that the jump's round off error is greater than 1.22 is P(x>1.22)=P(x>1.22)= . P(x>1.8∣x>0.5)=P(x>1.8∣x>0.5)= . Find the 54th percentile. Find the maximum for the lower quarter.
