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
22
with 200 citizens, the mean BMI was 23.3 kg/m and standard
deviation was 1.5 kg/m . It is reasonable to
assume the BMI distribution is a normal distribution.
-
(a) Find the point estimate of the population mean BMI one year ago.
-
(b) Calculate the sampling error at 90% confidence.
-
(c) Construct a 90% confidence interval estimate of the population mean BMI one year ago.
This city launched a healthy exercise program to reduce
citizen’s BMI after last year’s survey.
program effectively reduces the BMI of each citizen by 2.5%.
(d) Construct a 98% confidence interval estimate of the population
mean BMI after the healthy exercise
program. (Hint: find the updated sample mean and sample standard deviation of the BMI of the sample with 200 citizens selected last year)

programming in Python
The body mass index (BMI) is calculated as a person’s weight
(in lb) times 720, divided by the square of the person’s height (in
inches). A BMI in the range 19-25, inclusive, is considered
healthy. Write a program that inputs people’s weight and height,
then calculates a person’s BMI and print a message telling whether
they are above, within, or below the healthy range.
A formula for computing Easter in the years 1982-2048,
inclusive, is as follows:...

1. BMI or body mass index is a way to classify people according
to their height and weight. For all state employees, the state of
North Carolina is making everyone who has a BMI greater than 30 pay
extra for their health insurance. Assume that BMI is approximately
a normal distribution with a mean of 27.73 and a standard deviation
of 6.10 .
a. What percent of the state employees would have to pay extra
for health insurance?
b. Suppose...

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...

please show work
Body mass index (BMI) is computed as the ratio of weight in
kilograms to the square of the height in meters. The
distribution of BMI is approximately normal for females aged 30-39.
In this group, the mean BMI is 24.5, with a standard deviation of
3.3.
13) What proportion of females aged 30-39 has a BMI of 25 or
more?
14) Persons with a BMI of 30 or greater are considered
obese. What proportion of females aged 30-39 is...

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.
