Answer #1

Effects of exercise on blood pressure-

Your heart starts to pump harder and faster to circulate blood to deliver oxygen to your muscles. As a result, systolic blood pressure rises. It's normal for systolic blood pressure to rise to between 160 and 220 mm Hg during exercise.

But working out harder in high temperature may causes Systolic blood pressure to lower.Being in hot weather and glorious sunshine for a long period of time can actually lower blood pressure,Higher temperatures cause blood vessels to dilate, or expand, as the body tries to reduce its internal temperature. This creates more space in arteries and veins, causing a drop in blood pressure levels.

A group of five individuals with high blood pressure were given a new drug that was designed to lower blood pressure. Systolic blood pressure was measured before and after treatment for each individual. The mean and standard deviation for the before treatment were 168.6 and 9.3, respectively. The mean and standard deviation for the after treatment were 137.2 and 7.4. respectively. The 90% confidence for the mean reduction in systolic blood pressure is nearly ?

One with a systolic blood pressure greater than 129 is considered to have high blood pressure. A study recorded the systolic blood pressures of 14 randomly selected Americans, which yielded a mean of 131.57 with standard deviation 15.88. Conduct a hypothesis test to see if you can say that Americans, on average, have high blood pressure. 1.Write the hypotheses for this test. 2.What is the test statistic? 3.What is the p-value? 4.Using α = 0.05, decide whether or not to...

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 121 millimeters of mercury (mmHg) and standard deviation of 17. Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. Stage 1 high BP is specified as systolic BP between 140 and 160. Give your answers rounded to 4 decimal places. a. What is the probability that an adult in the USA has stage 2...

A nurse researcher hypothesized that back rubs lower systolic blood pressure in geriatric patients. She studied 9 nursing home patients. Blood pressures were measured before and then after a 10-minute back rub. Do we have evidence that systolic blood pressure is lower after the back rub for geriatric patients?

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 22 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 α=0.01 for the test. Assume that the systolic blood pressure levels are normally...
