Suppose that in a population of American adult coffee drinkers the change in heart rate ten minutes after drinking 6 ounces of coffee is normally distributed with a mean increase of 3.6 beats per minute and a standard deviation of 3.2 beats per minute. A negative change indicates a decrease in heart rate. What proportion of individuals in the population have a decrease in heart rate after drinking 6 ounces of coffee? The middle 80 percent of individuals have changes...

In what follows use any of the following tests/procedures: Regression, multiple regressions, confidence intervals, one-sided t-test or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval. Upload the data HeartRate_Exercise. These data are based on 45 randomly chosen high school students. SETUP: Is it reasonable to claim that students who exercise more have lower heart beat rate at rest. Given the data your job is to confirm or disprove this claim. 5. What test/procedure...

A physiological experiment was concluded to study the effect of various factors on a pulse rate. The participants took their own pulse. They then were asked to flip a coin. If their coin came up head, they were to run in place for 1 minute. Then everyone took their own pulse again. The dataset pulse.txt, available from Moodle, contains the following variables: ROW- id numbers, from 1 to 92; PULSE1- first pulse rate; PULSE2- second pulse rate; RAN-1=ran in place,...

The resting heart rate for an adult horse should average about μ = 42 beats per minute with a (95% of data) range from 18 to 66 beats per minute. Let x be a random variable that represents the resting heart rate for an adult horse. Assume that x has a distribution that is approximately normal. (a) The empirical rule indicates that for a symmetrical and bell-shaped distribution, approximately 95% of the data lies within two standard deviations of the...

"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle recovery angle" measures how well a fabric recovers from wrinkles. Higher is better. Here are data on the wrinkle recovery angle (in degrees) for a random sample of fabric specimens. Assume the populations are approximately normally distributed with unequal variances. A manufacturer believes that the mean wrinkle recovery angle for Hylite is better. A random sample of 25 Hylite (group 1) and 20 Permafresh (group...

Twenty-four males aged 25 to 29 were selected from the Framingham Heart Study. Twelve were smokers and 12 were non-smokers. The subjects were paired with one being a smoker and the other a non-smoker. Otherwise, each pair was similar with regard to age and physical characteristics. One piece of data that was collected on each of the pairs of subjects was systolic blood pressure readings. The data is shown here: Smoker Systolic BP 122 146 120 114 124 126 118...
