Chapter 1: Problem 31

Incarceration Rates (Example 7) The table gives the prison population and total population for a sample of states in 2014-15. (Source: The 2017 World Almanac and Book of Facts) $$ \begin{array}{|l|c|c|} \hline \text { State } & \text { Prison Population } & \text { Total Population } \\ \hline \text { California } & 136,088 & 39,144,818 \\ \hline \text { New York } & 52,518 & 19,795,791 \\ \hline \text { Illinois } & 48,278 & 12,859,995 \\ \hline \text { Louisiana } & 38,030 & 4,670,724 \\ \hline \text { Mississippi } & 18,793 & 2,992,333 \\ \hline \end{array} $$ Find the number of people in prison per thousand residents in each state and rank each state from the highest rate (rank 1\()\) to the lowest rank (rank 6). Compare these rankings of rates with the ranks of total numbers of people in prison. Of the states in this table, which state has the highest prison population? Which state has the highest rate of imprisonment? Explain why these two answers are different.

Short Answer

Expert verified
The solution to this exercise involves the calculation of imprisonment rates, ranking them, comparing these ranks with total prison populations, and presenting an explanation on observed differences.

Step by step solution

01

Calculate ratios

First, calculate the ratio of prisoners to total population for each state. This can be achieved by dividing the prison population by the total population and then multiplying the result by 1000 to get the rate per thousand residents. For example, for California: \( \frac{{136,088}}{{39,144,818}} \times 1000 = 3.47 \) prisoners per thousand residents.
02

Rank the ratios

After calculating the ratios for all states, list them from highest to lowest. The state with the highest ratio gets rank 1, and the state with the lowest ratio gets rank 6.
03

Compare the rankings

Once the ratios are ranked, compare these rankings with the ranks of total numbers of people in prison. Note any observations or insights you find interesting.
04

Make final observations

Identify the state with the highest prison population and the state with the highest rate of imprisonment. Then explain why these two answers are different. For instance, a state may have a lower total population but a higher proportion of that population incarcerated, leading to a higher imprisonment rate even though the total number of prisoners might be lower.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Prison Population Analysis
Understanding prison population analysis is essential for grasping the impact of the criminal justice system within a state. The prison population represents the number of individuals incarcerated at any given time. This number, however, cannot be looked at in isolation, as it is influenced by several factors, such as crime rates, judicial practices, and socio-economic conditions. When comparing different states, a significant consideration is to account for differences in total population, to provide context to raw numbers. Let's take the state of California as an example; with a prison population of 136,088, it may initially seem that California has a severe incarceration issue, but without considering its large population of over 39 million, this conclusion could be misleading. Through proper analysis, we can uncover patterns and identify whether a high prison population correlates with a large total population or indicates a higher propensity towards incarceration.
Rate Per Thousand Residents Calculation
The rate per thousand residents calculation balances the scale by considering the size of the state's population along with the prison population. This rate allows for a fair comparison between states of different sizes. The calculation involves dividing the 'Prison Population' by the 'Total Population' of each state, and then multiplying by 1000. This gives us the number of incarcerated individuals per thousand residents. For instance, in California, the calculation would be as follows:

\[ \frac{{136,088}}{{39,144,818}} \times 1000 = 3.47 \]
This means that for every thousand residents in California, approximately 3.47 are incarcerated. It is an essential step as it helps in identifying states with high incarceration rates irrespective of their total population.
Statistical Ranking
Statistical ranking helps us order states based on their incarceration rates. After determining the rate per thousand residents, states can be ranked from the highest rate of incarceration to the lowest. For instance, a state with the highest incarceration rate per thousand residents will be ranked 1, and the one with the lowest will be ranked 6. This ranking system offers a way to easily compare the level of imprisonment across different states by considering both the prison population and the state's total population size concurrently. Rankings provide a clear hierarchy and enable policymakers, researchers, and the general public to identify which states have more severe incarceration problems relative to their population size.
Data Interpretation
The process of data interpretation goes beyond mere calculation; it requires an analysis of what the numbers signify. For example, a state with the highest rate of imprisonment may not necessarily have the largest prison population. This is because 'rate' takes into account the total population, showing the propensity to incarcerate within the context of the total number of residents. Conversely, a larger prison population indicates the total number of people incarcerated without context to population size.

In our example, while California might have the largest prison population, it doesn't necessarily hold the highest rate of incarceration. Data interpretation enables us to understand these nuances and correlate them with socio-economic factors, crime rates, or legal policies. It raises more questions for inquiry; for example, does a high incarceration rate correspond to a higher crime rate, or does it reflect stringent judicial policies? It is an invitation to look deeper beyond numbers.

\(1.69\) Effects of Light Exposure A study carried out by Baturin and colleagues looked at the effects of light on female mice. Fifty mice were randomly assigned to a regimen of 12 hours of light and 12 hours of dark (LD), while another 50 mice were assigned to 24 hours of light (LL). Researchers observed the mice for two years, beginning when the mice were 2 months old. Four of the LD mice and 14 of the LL mice developed tumors. The accompanying table summarizes the data. (Source: Baturin et al., "The effect of light regimen and melatonin on the development of spontaneous mammary tumors in mice," Neuroendocrinology Letters, vol. 22 [December 2001]: \(441-447\) ) $$ \begin{array}{|l|r|r|} \hline & \text { LD } & \text { LL } \\ \hline \text { Tumors } & 4 & 14 \\ \hline \text { No tumors } & 46 & 36 \\ \hline \end{array} $$ a. Determine the percentage of mice that developed tumors from each group (LL and LD). Compare them and comment. b. Was this a controlled experiment or an observational study? How do you know? c. Can we conclude that light for 24 hours a day causes an increase in tumors in mice? Why or why not?

Milk and Cartilage (Example 10) Cartilage is a smooth, rubber-like padding that protects the long bones in the body at the joints. A study by Lu et. al. in Arthritis Care \& Research found that women who drank one glass of milk daily had \(32 \%\) thicker, healthier cartilage than women who did not. Researchers obtained information on milk consumption through questionnaires and measured cartilage through x-rays. In the article, researched conclude, "Our study suggested that frequent milk intake may be associated with reduced OA progression in women." (Source: Lu et al., "Milk consumption and progression of medial tibiofemoral knee osteoarthritis: Data from the osteoarthritis initiative," Arthritis Care \& Research, vol. 66 [June 2014]: 802-809, https://doi.org/10.10002/acr.22297 Does this study show drinking milk causes increased cartilage production? Why or why not?
