Easy reading? Refer to Exercise 46. Describe the shape of the distribution.

Short Answer

Expert verified

Roughly symmetric

Single peak

No gaps

Step by step solution

01

Step 1. Given information

Here are data on the lengths of the first 25 words from Toni Morrison鈥檚 Song of Solomon:

02

 Step 2. make a number line for each piece of data Put a dot on the number line above the corresponding number.

03

 Step 3. The shape of the distribution.  

The peak in the dotplot is roughly in the middle of the graph, indicating that the distribution is roughly symmetric.

We notice that the distribution has a single peak at 7, and there appear to be no (large) gaps in the dotplot.

Roughly symmetric

Single peak

No gaps

Far from home A survey asked first-year college students, 鈥淗ow many miles is this college from your permanent home?鈥� Students had to choose from the following options: 5 or fewer, 6 to 10, 11 to 50, 51 to 100, 101 to 500, or more than 500. The side-by-side bar graph shows the percentage of students at public and private 4-year colleges who chose each option. Write a few sentences comparing the distributions of distance from home for students from private and public 4-year colleges who completed the survey.

AP庐 exam scores The table gives the distribution of grades earned by students taking the AP庐 Calculus AB and AP庐 Statistics exams in 2016

Part (a). Make an appropriate graphical display to compare the grade distributions for AP庐 Calculus AB and AP庐 Statistics.

Part (b). Write a few sentences comparing the two distributions of exam grades.

Healthy streams Nitrates are organic compounds that are a main ingredient in fertilizers. When those fertilizers run off into streams, the nitrates can have a toxic effect on fish. An ecologist studying nitrate pollution in two streams measures nitrate concentrations at 42 places on Stony Brook and 42 places on Mill Brook. The parallel dotplots display the data. Compare the distributions of nitrate concentration in these two streams.

The histogram shows the heights of 300 randomly selected high school students. Which of the following is the best description of the shape of the distribution of heights?

b. Roughly symmetric and double-peaked

c. Roughly symmetric and multi-peaked

d. Skewed to the left

e. Skewed to the right
