A certain ultrasound device can measure a fetal heart rate as low as 50 beats per minute. This corresponds to the surface of the heart moving at about 4.0 x 10-4 m/s. If the probe generates ultrasound that has a frequency of 2.0 MHz (1 MHz = 1 megahertz = 106 Hz), what frequency shift must the machine be able to detect? Use v sound = 1540 m/s for the speed of sound in human tissue.

Measure heart rate in beats per minute, respiration rate in breaths per minute and blood pressure...

Measure heart rate in beats per minute, respiration rate in breaths per minute and blood pressure as systolic/diastolic (these measurements should look like 120/70). Your pulse rate should be measured for at least 15 seconds and your respiration rate should be measured for at least 30 seconds. Try taking your blood pressure as quickly as you can. Perform the following experiments and enter your data on the Report Page. 1. While you are resting, either or sitting or lying down,...

For a certain group of individuals, the average heart rate is 80 beats per minute, with a standard deviation of 3 beats. If a subject is selected at random, find the following, show your work: a. between 75 and 85 beats per minute. b. between 81 and 86 beats per minute. c. between 76 and 79 beats per minute.

Measure your own heart rate in beats per minute. Post your individual results and corresponding z-score using a population mean resting heart rate of 73 beats per minute and standard deviation of 8 beats per minute. Be sure to use the formula z equal fraction numerator Y minus italic mu over denominator italic sigma end fraction to calculate your z score. Use the StandardNormalZTables(1).pdf to find your resting heart rate percentile ranking. Do you think your resting hear rate is...

A multiple regression model is to be constructed to predict the heart rate in beats per minute (bpm) of a person based upon their age, weight and height. Data has been collected on 30 randomly selected individuals: hide data Heart Rate (bpm) Age (yrs) Weight (lb) Height (in) 78 23 245 70 91 44 223 68 79 42 178 67 60 33 200 58 57 25 99 68 59 35 123 64 78 30 204 62 98 56 200 63...

The heart rate of a fetus, in beats per second (bps), is an indicator of baby gender. To determine the gender of his kid, Resh decide to buy an at-home heart monitor. For the next 30 days, Resh measures the heart rate of the fetus. The average heart rate measured over the past 30 days is 129.5 bps. Previous research established that the population’s standard deviations is 20 bps. Also, the previous research suggest that fetal heart rate is normally...

It is generally accepted that the mean heart rate (beats per minute; bpm) of an adult human is between 65 bpm and 75 bpm, with a single average value of 72 bpm. In this case study you will test the hypothesis that the average heart rate of adults is 72 bpm (μ = 72 bpm) for all adults and then separately by gender. The distribution of heart rates is approximately normal. 1.Complete the hypothesis test for all adults(Males and Females)...

Among a sample of 16 people, the average heart rate was 69.0 beats per minute with a standard deviation 4.3 beats per minute. We are interested in the mean heart rate of the population. We assume that the heart rate is normally distributed, and that the population standard deviation is 4.8 beats per minute. At 95% confidence, what is the error bound?

Question 1. The heart rate of 20 randomly selected adults was on average 85 beats per minute (bpm) with a standard deviation of 5 bpm. Build a 95% confidence interval for the mean heart rate of adults in the population. Interpret the interval you have created

Mr. Jones’s heart rate is 54 beats per minute. Tony is about to give Mr. Jones his scheduled atenolol dose. When Tony scans Mr. Jones’s armband and the medication bar codes, the computer warns him that atenolol should not be given to a patient with a heart rate less than 60 beats per minute. What should Tony do?
