Ages of Head Start Program Students The Head Start Program provides a wide range of services to low-income children up to the age of 5 and their families. Its goals are to provide services to improve social and learning skills and to improve health and nutrition status so that the participants can begin school on an equal footing with their more advantaged peers. The distribution of ages for participating children is as follows: 4% five-year-olds, 52% four-year-olds, 34% three-year-olds, and 10% under three years. When the program was assessed in a particular region, it was found that of the 200 participants, 10 were 5 years old, 96 were 4 years old, 84 were 3 years old, and 10 were under 3 years. Is there sufficient evidence at α=0.05 that the proportions differ from that of the program? Use the P-value method. Compute the test value. Round your answer to at least three decimal places χ2 = Make the decision.
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.
