For the questions on this project assume that the mean systolic blood pressure of adults in

America is 120 millimeters of mercury (mmHg) with a standard deviation of 5.6 mmHg. Also

assume the variable is normally distributed.

1) Your company develops a new treatment for high blood pressure. You want to test it on

people who are in the 90th

percentile or higher (people who have a higher systolic blood

pressure than 90% of other Americans). What is the cut-off blood pressure for this group –

what is the lowest systolic blood pressure a person could have to be considered for this trial?

2) In a group of 1,000 randomly selected adult Americans, about how many do we expect to

have a systolic blood pressure of 110 mmHg or less

In a sample of 40 US adults, the mean systolic blood pressure was 127.3 mmHg. Assume that the standard deviation for the systolic blood pressure of all US adults is 20 mmHg. 1. Find a 90% confidence interval for the mean systolic blood pressure for all US adults. 2. interpret the confidence interval you found in problem 1. 3. how large of a sample would you need so that the margin of error in a 90% confidence interval is at...

Assume that the mean systolic blood pressure of normal adults is 120 milliliters of mercury (mmHg) and the standard deviation is 5.6. Assume the variable is normally distributed. a) If an individual is selected, find the probability that the individual’s pressure will be between 118 and 122.8 mmHg. b) If a sample of 40 adults is randomly selected, find the probability that the sample mean will be more than 121 mmHg.
