Student survey A survey of a large high school class asked the following questions:

(i) Are you female or male? (In the data, male = 0, female = 1)

(ii) Are you right-handed or left-handed? (In the data, right = 0, left = 1)

(iii) What is your height in inches?

(iv) How many minutes do you study on a typical weeknight?

The figure below shows histograms of the student responses, in scrambled order and without scale markings. Which histogram goes with each variable? Explain your reasoning.

Short Answer

Expert verified

Histogram (c) goes with question (i)

Histogram (d) goes with question (iv)

Histogram (b) goes with question (ii)

Histogram (a) goes with question (iii)

Step by step solution

01

Given information

(i)Female or male (In the data, male = 0, female = 1)

(ii)Right-handed or left -handed (In the data, right = 0, left = 1)

(iii)Height in inches.

(iv)The study time at weeknight.

02

Concept

A histogram is a graphing tool that is extensively used. It's used to summarise discrete or continuous data measured on a scale of one to ten. It's a standard way of exhibiting essential data distribution aspects in an easy-to-understand format.

03

Explanation

The histogram (a) corresponds to question (iii), and it depicts the distribution of height in inches, since most of the respondents from a large high school class belong to the same group, and only a few are taller than average.

The histogram (b) corresponds to question (ii), indicating whether a pupil in a large high school class is right- or left-handed. People are normally right-handed since right is 0 and left is 1. The histogram (b) reveals that the majority of them are right-handed, which is in line with the general trend, and that only a handful are left-handed.

The histogram (c) corresponds to query I in that it categorizes individuals from a large high school class by gender. There are more ladies in the class than males because male = 0 and female = 1.

The histogram (d) corresponds to question (iv), which is how much time each student in a large high school class spends on a typical weekday. Variations in the distribution are conceivable owing to differences in study duration. The histogram's distribution is symmetric.

What do they measure? For each of the following summary statistics, decide (i) whether it could be used to measure center or spread and (ii) whether it is resistant.

Here, once again, is the stem plot of travel times to work for 20randomly selected New Yorkers. Earlier, we found that the median was 22.5

Use your calculator to find the mean travel time. Was your answer to Question 1 correct?

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

Do women study more than men? We asked the students in a large first-year college class how many minutes they studied on a typical weeknight. Here are

the responses of random samples of 30 women and 30 men from the class:

(a) Examine the data. Why are you not surprised that most responses are multiples of 10 minutes? Are there any responses you consider suspicious?

(b) Make a back-to-back stem plot to compare the two samples. Does it appear that women study more than men (or at least claim that they do)? Justify your answer.

The figure displays computer output from Data Desk for data on the amount spent by 50 grocery shoppers.

(a) What would you guess is the shape of the distribution based only on the computer output? Explain.

(b) Interpret the value of the standard deviation.

(c) Are there any outliers? Justify your answer.
