Question Number 13

A Scientist is researching whether or not body mass index (BMI) to the systolic blood pressure(SBP). He collects the random sample of 8 different patients. The results are shown in the table below.

Table 8

BMI 21 23 24 25 20 28 26 27
SBP(mm Hg) 118 114 119 131 111 124 117 118

a. Draw a scatter diagram

b. Explain why a linear regression model may be appropriate to describe the relationship between BMI and SBP.

c. Find the equation of regression line

d. Draw the regression line on your scatter diagram.

e. Estimate the value of BMI if the value of SPB is 120 mm Hg

The Body Mass Index (BMI) is a calculation used to categorize whether a person’s weight is at a healthy weight for a given height. The formula is as follows:                 bmi = kilograms / (meters2)                 where kilograms = person’s weight in kilograms, meters = person’s height in meters BMI is then categorized as follows: Classification BMI Range Underweight Less than 18.5 Normal 18.5 or more, but less than 25.0 Overweight 25.0 or more, but less than 30.0 Obese 30.0...

Question 2 The Body Mass Index (BMI) is a value calculated based on the weight and the height of an individual. In a small European city, a survey was conducted one year ago to review the BMI of the citizens. In the sample with 200 citizens, the mean BMI was 23.3 kg/m2 and standard deviation was 1.5 kg/m2 . It is reasonable to assume the BMI distribution is a normal distribution. (a) Find the point estimate of the population mean...

A number of studies have shown a relationship between obesity or body mass index (BMI) and endometrial cancer. A study was conducted among post-menopausal women aged 50-74 years. BMI was used to measure the obesity. BMI >= 30 were interpreted as obese and BMI<30 were as non-obese. Of the total 1055 eligible cases identified through the five regional cancer registries in Sweden, 789 participated in the study but only 592 had complete data to be used in the analysis of...

Design a modular program that calculates and displays a person's body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calculated with the following formula: BMI=Weight*703/Height^2. I need help making this to Java to just calculate BMI.

Body mass index (BMI) is a reliable indicator of body fat for most children and teens. BMI is calculated from a child’s weight and height and is used as an easy-to-perform method of screening for weight categories that may lead to health problems. For children and teens, BMI is age- and sex-specific and is often referred to as BMI-for-age. The Centers for Disease Control and Prevention (CDC) reports BMI-for-age growth charts for girls as well as boys to obtain a...

The data file contains the Body Mass Index (BMI) for a sample of men and a sample of women. Two of the columns, OW_male and OW_female code the BMI values as: 0 - if BMI ≤ 25.4 (these are considered “not overweight”); 1 - if BMI >= 25.5 (these are considered “overweight”). (a) Test whether there is sufficient evidence to show that the proportion of overweight males (proportion of males who are overweight) is different than the proportion of overweight...

If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI? Alternatively, find an article that uses regression analysis to study a medical concern. In that study, what was the dependent variable and what was the independent variable(s)? Further, how would you use...
