d) The School District proceeded with the study by randomly selecting students for the survey. The results showed that 147 out of 200 students were satisfied with the food under this contract. Would it be appropriate to infer that these results adequately reflect the population? Provide an explanation for your response.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question number 2 Part D only
Transcribed Image Text:2. In response to nutrition concerns raised last year about food served in school cafeterias, the Smallville
School District entered into a one-year contract with the Healthy Alternative Meals (HAM) company. Under
this contract, the company plans and prepares meals for all elementary, middle, and high school students,
with a focus on good nutrition (there are 2500 total students in the district). The school administration would
like to survey the students in the district to estimate the proportion of students who are satisfied with the
food under this contract.
a) Is this an observational study or an experiment? Explain your reasoning.
b) Describe a simple random sampling procedure that the administrators could use to select 200 students
from the 2,500 students in the district.
c) If a stratified random sampling procedure is used, give one example of an effective variable on which to
stratify in this survey. Explain your reasoning.
d) The School District proceeded with the study by randomly selecting students for the survey. The results
showed that 147 out of 200 students were satisfied with the food under this contract. Would it be appropriate
to infer that these results adequately reflect the population? Provide an explanation for your response.
