The body mass index of an individual is a measure used to judge whether an individual is overweight or not. A BMI between 20 and 25 indicated a normal weight. In a survey of 750 men and 750 women, the Gallup organization found that 207 men and 269 women were normal weight. Based on this sample we wish to state whether there is a difference in the proportion of men and women who are normal weight.

Write the desired hypothesis.

Check the conditions of a hypothesis test on this data.

Sketch the distribution curve, critical value(s) and your test statistics if we use 0.08.

What is your conclusion?

Your body mass index (BMI) is your weight in kilograms divided by the square of your height in meters. High BMI is a common but controversial indicator of overweight or obesity. A study by the National Center for Health Statistics found that the BMI of American young men (ages 20-29) is approximately Normal with mean 25.8 and standard deviation 4.2. To have a BMI higher than 90% of all men aged 20-29, what would your BMI would need to be?

The body mass index (BMI) of a person is the person’s weight divided by the square of his or her height. It is an indirect measure of the person’s body fat and an indicator of obesity. Results from surveys conducted by the Centers for Disease Control and Prevention (CDC) showed that the estimated mean BMI for US adults increased from 25.0 in the 1960–1962 period to 28.1 in the 1999–2002 period. [Source: Ogden, C., et al. (2004). Mean body weight,...

Write a modular program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula BMI = weight * 703/height2 Where weight is measured in pounds and height is measured in inches. The program should ask the user to enter his or her weight and height and then display the user’s BMI. The...

BMI (Body Mass Index) is your weight in kilograms divided by the square of your height in meters. BMI for women is approximately Normal with mean 26.8 and standard deviation 7.4; If you wanted to classify the bottom 15% of all women as underweight and top 15% of all women as “obese” what BMI indices would you need to separate these two categories?

8. We know that the mean weight of men is greater than the mean weight of women, and the mean height of men is greater than the mean height of women. A person’s body mass index (BMI) is computed by dividing weight (kg) by the square of height (m). Use α = 0.05 significance level to test the claim that females and males have the same mean BMI. Below are the statistics for random samples of females and males. Female...

Investigators studied the relationship between screen time (measured in hours/week) and body- mass-index, BMI= wt/ht2 (wt = weight in kg and ht = height in meters), in men age 25 - 45 . They surveyed 6234 U.S. men in this age group, the scatter diagram for the data was homoscedastic and the BMI data was approximately normally distributed both unconditionally and in each vertical strip. The investigators generated the following summary statistics: X=35 SDX=12 Y = 27 SDY = 6...

Sample Statistic Value of sample statistic Sample mean () Body Mass Index (BMI) 21.65 Sample standard deviation (s) of Body Mass Index (BMI) 4.33 Sample size 92 (13 points) You will use information about the body mass index (BMI) variable for the sample of adolescent girls to perform a hypothesis test. You will test the claim that the mean BMI for all adolescent girls is 21.0. The null hypothesis is H0 : µ = 21.0. State the alternate hypothesis for...

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 BMI one year...

In Exercises 5–20, assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal.
