Question

Life at work (1.1) The University of Chicago’s General Social Survey asked a representative sample of adults this question: “Which of the following statements best describes how your daily work is organized? (1) I am free to decide how my daily work is organized. (2) I can decide how my daily work is organized, within certain limits. (3) I am not free to decide how my daily work is organized.” Here is a two-way table of the responses for three levels of education:240 Is there an association between level of education and freedom to organize one’s work? Give graphical and numerical evidence to support your answer.

Short answer

P (at least one of two underweight) = $0.245$

Step-by-step solution

Step 1. Given Information

$$\begin{gathered} \mu =26.8 \\ \sigma =7.4 \end{gathered}$$

Step 2. Concept used

Complement rule: $P(notA)=1-P\left(A\right)$

Step 3. Calculation

Each bar's width must be equal, and its height must be equal to the frequency. $P(notA)=1-P\left(A\right)$

It should be noticed that the response level distribution$(1,2,3)$ for each category of maximum degree completed is not the same (proportion of response level $3$ is lower for bachelor's degree than or less than high school degree).

This implies that there is a link between one's educational degree and their response to the flexibility to organize one's work.
