Chapter 1: Q T1.2. (page 78)

Consumers Union measured the gas mileage in miles per gallon of 38 vehicles from the same model year on a special test track. The pie chart provides information about the country of manufacture of the model cars tested by Consumers Union. Based on the pie chart, we conclude

(a) Japanese cars get significantly lower gas mileage than cars from other countries.

(b) U.S. cars get significantly higher gas mileage than cars from other countries. (c) Swedish cars get gas mileages that are between those of Japanese and U.S. cars.

(d) Mercedes, Audi, Porsche, and BMW represent approximately a quarter of the cars tested.

(e) More than half of the cars in the study were from the United States.

Short Answer

Expert verified

The correct option is (e) More than half of the cars in the study were from the United States.

Step by step solution

01

Given Information

The figure given is

02

Concept

A statistical graph or chart is a visual representation of statistical data in graphical form.

03

Explanation

We can deduce from the pie graph that options more than half of the cars in the study were from the United States. Therefore, option (e) is the most appropriate conclusion.

C-sections Do male doctors perform more cesarean sections (C-sections) than female doctors? A study in Switzerland examined the number of cesarean sections (surgical deliveries of babies) performed in a 100. Section 1.3 Describing Quantitative Data with Numbers 73 year by samples of male and female doctors. Here are summary statistics for the two distributions:

(a) Based on the computer output, which distribution would you guess has a more symmetrical shape? Explain.

(b) Explain how the IQRs of these two distributions can be so similar even though the standard deviations are quite different.

(c) Does it appear that males perform more C-sections? Justify your answer

Which of the following is least affected if an extreme high outlier is added to your data?

(a) Median

(b) Mean

(c) Standard deviation

(d) Range

(e) Maximum

Feeling sleepy? The first four students to arrive for a first-period statistics class were asked how much sleep (to the nearest hour) they got last night. Their responses were 7,7,9,and 9

(a) Find the standard deviation from its definition. That is, find the deviations of each observation from the mean, square the deviations, then obtain the variance and the standard deviation.

(b) Interpret the value of sx you obtained in (a).

(c) Do you think it鈥檚 safe to conclude that the mean amount of sleep for all 30 students in this class is close to 8 hours? Why or why not?

How can we help wood surfaces resist weathering, especially when restoring historic wooden buildings? In a study of this question, researchers prepared wooden panels and then exposed them to the weather. Here are some of the variables recorded: type of wood (yellow poplar, pine, cedar); type of water repellent (solvent-based, water-based); paint thickness (millimeters); paint color (white, gray, light blue); weathering time (months).

Identify each variable as categorical or quantitative.

The mean salary of all female workers is \(35,000 The mean salary of all male workers is \)41,000 What must be true about the mean salary of all workers?

(a) It must be \(38,000

(b) It must be larger than the median salary.

(c) It could be any number between \)35,000 and \(41,000

(d) It must be larger than \)38,000

(e) It cannot be larger than $40,000
