You are making a two-way frequency table of 5 fruit preferences among a survey sample of girls and boys. What are the dimensions of the table you would make? How many entries would you need to fill the table with frequencies and totals?

In creating a model of our living planet, scientists need to consider four major Earth systems. Briefly describe these four systems, and then explain why it is difficult to study these systems individually.

Use the table of frequency data.

$$\scriptstyle\begin{array}{c} \\ \text{Class Survey of Favorite Colors} \\ \begin{array}{|l|c|c|c|c|c|c|c|} \hline \text { Favorite Color } & \text { Red } & \text { Orange } & \text { Yellow } & \text { Green } & \text { Blue } & \text { Purple } & \text { Total } \\ \hline \text { Frequency } & 2 & 5 & 1 & 6 & 8 & 2 & 24 \\ \hline \end{array} \end{array}$$

Complete the relative frequency table for this data using decimals rounded to the nearest thousandth.

$$\scriptstyle\begin{array}{c} \\ \text{Class Survey of Favorite Colors} \\ \begin{array}{|l|c|c|c|c|c|c|c|} \hline \text { Favorite Color } & \text { Red } & \text { Orange } & \text { Yellow } & \text { Green } & \text { Blue } & \text { Purple } & \text { Total } \\ \hline \text { Relative Frequency } & & & & & & & \\ \hline \end{array} \end{array}$$

A researcher surveyed 135 people, 85 females and 50 males. The researcher asked each person which of the following types of movies they preferred: action, comedy, or drama. Complete the table.

$$\begin{array}{c}\\ \text{Favorite Type of Movie} \\ \begin{array}{|c|c|c|c|c|} \hline \text { Gender } & \text { Action } & \text { Comedy } & \text { Drama } & \text { Total } \\ \hline \text { Female } & 35 & & 18 & \\ \hline \text { Male } & 12 & 28 & & \\ \hline \text { Total } & & & 28 & \\ \hline \end{array} \end{array}$$

Decomposers are an important part of many biogeochemical cycles. Some carry out aerobic respiration and some use anaerobic respiration as they break down organic matter. Explain why decomposers are so crucial for the cycling of matter in ecosystems. Cite specific examples to support your answer.

Look at each variable. Is the variable best represented by categorical data? Choose Yes or No for each variable. A. Favorite song B. Car color C. Weight

Complete the two-way frequency table. Interpret the meaning of the number in the starred cell of the table.

$$\begin{array}{c} \\ \qquad \qquad\text{Preferred Mode of Transportation} \\ \begin{array}{|c|c|c|c|c|} \hline \text { Age } & \text { Bike } & \text { Car } & \text { Bus } & \text { Total } \\ \hline \text { Adults } & 25 & 3 & 12 & \\ \hline \text { Teenagers } & 5 & 28 & 12 & \\ \hline \text { Total } & & & & \\ \hline \end{array} \end{array}$$

A consumer eats $1500 \mathrm{~J}$ of food energy. The consumer uses 15 percent of the food energy for new biomass and the rest for cellular respiration and waste. Use this information to answer the following questions:

a. How many joules of food energy were converted into new biomass?

b. How many joules of food energy are lost to cellular respiration and waste?

c. What percentage of the food energy was lost to cellular respiration and waste?

Identify whether the given data is categorical or quantitative. gold medal, silver medal, bronze medal ______ 100 m, 200 m, 400 m _____

What are the two types of laws King defines? What is the difference between the two?

Maria feels beleaguered on the first day of school. Does her facial expression show confidence or panic? Why?

The flowers you received last week appear wizened. What will you do with them? Why?

How are photosynthesis and cellular respiration related?

Select the statement that describes the relationship between cellular respiration and photosynthesis.

a. The overall reactants and products produced in photosynthesis are consumed in cellular respiration and vice versa. Photosynthesis uses light energy to build carbon-based molecules and release oxygen; cellular respiration uses oxygen to break down carbon-based molecules to release energy.

b. Photosynthesis and cellular respiration consume and produce the same reactants and products. Photosynthesis and carbon dioxide both produce carbon-based molecules that are then broken down to release stored energy.

c. The processes of storing energy in carbon-based molecules during photosynthesis and breaking down those molecules to release energy during cellular respiration both occur in the same organelle.

d. All of the energy and matter produced during photosynthesis is consumed during cellular respiration and vice versa.
