Loretta, who turns eighty this year, has just learned about blood pressure problems in the elderly and is interested in how her blood pressure compares to those of her peers. Specifically, she is interested in her systolic blood pressure, which can be problematic among the elderly. She has uncovered an article in a scientific journal that reports that the mean systolic blood pressure measurement for women over seventy-five is 133.5 mmHg, with a standard deviation of 6.1 mmHg. Assume that...

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters, for a sample of 6 adults. The following table presents the results. The least-squares regression line y =be+b,x=111.1246 -0.2740x, s.7.0225868, (-x) = 187.33, and x = 119.67 are known for this data. Diastolic Systolic...

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 121 and standard deviation of 23. Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. a. Around what percentage of adults in the USA have stage 2 high blood pressure? Give your answer rounded to two decimal places. % b. If you sampled 2000 people, how many would you expect to have BP> 160?...

The systolic blood pressure for female diabetics between the ages of 30 and 34 has mean 131 mmHg and standard deviation = 12 mmHg. a. Do you have enough information to compute (at least approximately) the proportion of individuals in this population who have blood pressure greater than 150 mmHg? If so, provide this value. If not, explain why. b. Do you have enough information to compute (at least approximately) the probability that the average blood pressure in a random...

When 14 different second-year medical students measured by the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Assuming that the population standard deviation is known to be 15 mmHg, use a 0.05 significance level to test the claim that the mean blood pressure level is less than 140 mmHg. Hyper- tension is defined to be a blood pressure level that is too high because it is 140 mmHg or greater. Assume the blood...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d = (blood pressure before taking new drug)-(blood pressure after taking new drug). Use a significance level of a = 0.05 for the test. Assume that the systolic blood...
