Introduction

A contingency table is a statistical tool used to display the relationship between two categorical variables. In this case, we have a partially filled contingency table that provides the frequencies of data on age (in years) and sex from the residents of a retirement home. The table is incomplete, but it still offers valuable insights into the distribution of age and sex among the residents. In this article, we will delve into the analysis of the contingency table, exploring the frequencies of age and sex, and discussing the implications of the data.

The Contingency Table

The contingency table is as follows:

	60-69	70-79	Over 79	Total
Male	12	1	5	18
Female
Total

Analysis of Age Distribution

The contingency table shows that the majority of the residents are between the ages of 60-69, with 12 males in this age group. The next age group, 70-79, has only 1 male resident, indicating a significant decline in the number of residents in this age group. The age group "Over 79" has 5 male residents, which is a relatively small number compared to the 60-69 age group.

Analysis of Sex Distribution

The contingency table does not provide information on the number of female residents in each age group. However, we can infer that the number of female residents is likely to be higher than the number of male residents, given the fact that the total number of residents is not provided. This suggests that the sex distribution may be skewed towards females.

Discussion Category: Mathematics

The contingency table is related to the discussion category of mathematics, which may seem unrelated to the topic of age and sex distribution in a retirement home. However, the table can be used to illustrate mathematical concepts such as contingency tables, probability, and statistics.

Mathematical Concepts

The contingency table can be used to illustrate the following mathematical concepts:

Contingency Tables: A contingency table is a statistical tool used to display the relationship between two categorical variables. In this case, the contingency table displays the relationship between age and sex.
Probability: The contingency table can be used to calculate probabilities, such as the probability of a resident being male and between the ages of 60-69.
Statistics: The contingency table can be used to calculate statistical measures, such as the mean and median age of the residents.

Conclusion

In conclusion, the partially filled contingency table provides valuable insights into the distribution of age and sex among the residents of a retirement home. The table shows that the majority of the residents are between the ages of 60-69, with 12 males in this age group. The sex distribution may be skewed towards females, given the fact that the total number of residents is not provided. The contingency table can be used to illustrate mathematical concepts such as contingency tables, probability, and statistics.
