According to Healthdata.org, about 30% of American children are
considered obese or overweight. What is the probability that in a
random sample of 500 children, 25% or less will be obese or
overweight? To assist you, please fill out the following:
a) What is p?
b) Verify that the sample is large enough to meet the
requirements of the CLT:
c) Calculate the standard error (SE).

Researchers have hypothesized that the distribution of the
weight categories (underweight, normal, overweight\obese) of high
school boys is changing over time. In 2006, the proportion of a
large sample of high school boys was collected in 2006, resulting
in the following proportions (Table 1):
Table 1: Distribution of weights of high school boys 2006
Weight classification (BMI range)
Proportion of high school boys
Underweight (<18 kg/m2)
4.8%
Normal weight (18-25 kg/m2)
80.4%
Overweight/obese (>25 kg/m2)
14.7%

In the cohort study by Wilding et al. (2020), children aged 4–5
years at baseline (10–11 years at follow-up) had height and weight
measured at school at both time points. Environmental features
included walkability, relative density of unhealthy food outlets,
spaces for social interaction, natural greenspace coverage,
supermarket density and measures of air pollution. It aimed to
examine if such environmental characteristics at birth were related
to the likelihood of overweight and obesity in childhood. Explain
what the advantages and...

1)You are now a grown-up and have 2 children:
Nicole, aged 6, and Yuri, aged 8. They want to sell lemonade in the
front yard for $.50 a glass. You agree that this would be a good
experience in entrepreneurship, and tell them that you will loan
them the money but they have to pay for their materials and
equipment (the labor, however, is free.)
The lemonade mix costs $4.79 a package, and will make 100
glasses of lemonade. The...
