Mercury in tuna Is there a difference in the mercury concentration of light tuna and albacore tuna? Use the parallel boxplots and the computer output to write a few sentences comparing the two distributions.

Short Answer

Expert verified

There appears to be a distinction.

Step by step solution

01

Step 1. Given information

Mercury in tuna Is there a difference in the mercury concentration of light tuna and albacore tuna

02

Step 2. a couple of sentences comparing the two distributions

There is a difference in mercury concentration because the mean, minimum, first quartile Q1, median, and third quartileQ3for Albacore tuna are higher than for light tuna.

However, we note that the maximum for Light tuna is higher than for Albacore tuna, despite the fact that Light tuna has many outliers and Albacore tuna has only one.

Light tuna has a much wider range of mercury concentrations than Albacore tuna.

As a result:

There appears to be a distinction.

Superpowers A total of 415 children from the United Kingdom and the United States who completed a survey in a recent year were randomly selected. Each student鈥檚 country of origin was recorded along with which superpower they would most like to have: the ability to fly, ability to freeze time, invisibility, superstrength, or telepathy (ability to read minds). The data are summarized in the following table.

(a) What proportion of students in the sample are from the United States?

(b) Find the distribution of superpower preference for the students in the sample using relative frequencies.

(c) What percent of students in the sample are from the United Kingdom and prefer telepathy as their superpower preference?

Popular car colors Favorite car colors may differ among countries. The side-by-side bar graph displays data on the most popular car colors in a recent year for North America and Asia. Write a few sentences comparing the distributions.

The following bar graph shows the distribution of favorite subject for a sample of 1000 students. What is the most serious problem with the graph?

(b) This distribution should be displayed with a pie chart.

(c) The vertical axis should show the percent of students.

Die rolls Imagine rolling a fair, six-sided die 60 times. Draw a plausible graph of the distribution of die rolls. Should you use a bar graph or a histogram to display the data?

A smash or a hit?Researchers asked 150 subjects to recall the details of a car accident they watched on video. Fifty subjects were randomly assigned to be asked, 鈥淎bout how fast were the cars going when they smashed into each other?鈥� For another 50 randomly assigned subjects, the words 鈥渟mashed into鈥� were replaced with 鈥渉it.鈥� The remaining 50 subjects鈥攖he control group鈥攚ere not asked to estimate speed. A week later, all subjects were asked if they saw any broken glass at the accident (there wasn鈥檛 any). The table shows each group鈥檚 response to the broken glass question.

(a) What proportion of subjects were given the control treatment?

(b) Find the distribution of responses about whether there was broken glass at the accident for the subjects in this study using relative frequencies.

(c) What percent of the subjects were given the 鈥渟mashed into鈥� treatment and said they saw broken glass at the accident?
