Description
suppose we want to establish the mean number of hours per day population that students read while on vacation. We asked 10 students how many hours they read each day during their vacation and recorded as 4,6,8,9,2,6,10,5,11 and 12, we would then choose to calculate an interval of trust of 99% for mean population

Applied Mathematics Question
1-1 Discussion: Population, Samples, and BiasIn
real-life applications, statistics helps us analyze data to extract
information about a population. In this module discussion, you will take
on the role of Susan, a high school principal. She is planning on
having a large movie night for the high school. She has received a lot
of feedback on which movie to show and sees differences in movie
preferences by gender and also by grade level.She knows if the wrong movie is shown, it could reduce event turnout
by 50%. She would like to maximize the number of students who attend and
would like to select a PG-rated movie based on the overall student
population's movie preferences. Each student is assigned a classroom
with other students in their grade. She has a spreadsheet that lists the
names of each student, their classroom, and their grade. Susan knows a
simple random sample would provide a good representation of the
population of students at their high school, but wonders if a different
method would be better.You can review the student demographics here: Module One Discussion Data.In your initial discussion post, specifically address the following:Introduce yourself and describe a time when you used data in a
personal or professional decision. This could be anything from analyzing
sales data on the job to making an informed purchasing decision about a
home or car.Describe an example of a sample of this student population that would not represent the population well.Describe another example of a sample that would represent the population well.Finally, describe the relationship of a sample to a population and
classify your two samples as random, cluster, stratified, or
convenience.In your response posts to at least two peers, discuss the following:Choose two different sampling methods from among
your peers' responses. Then, identify bias in each peer's sample and
explain how you think they could remove it
