Chapter 1: Problem 1

Experimental Units Identify the experimental units on which the following variables are measured: a. Gender of a student b. Number of errors on a midterm exam c. Age of a cancer patient d. Number of flowers on an azalea plant e. Color of a car entering a parking lot

Short Answer

Expert verified
Answer: a. Individual student, b. Individual exam, c. Individual cancer patient, d. Individual azalea plant, e. Individual car.

Step by step solution

01

a. Gender of a student

The experimental unit for the variable "gender of a student" would be an individual student, as the gender is being measured on each student.
02

b. Number of errors on a midterm exam

The experimental unit for the variable "number of errors on a midterm exam" would be the exams taken by individual students. The number of errors is being measured on each individual exam, which represents one experimental unit.
03

c. Age of a cancer patient

The experimental unit for the variable "age of a cancer patient" would be an individual cancer patient. The age is being measured on each cancer patient, making them the experimental unit.
04

d. Number of flowers on an azalea plant

The experimental unit for the variable "number of flowers on an azalea plant" would be the individual azalea plant. The number of flowers is being measured on each azalea plant, making the plant the experimental unit.
05

e. Color of a car entering a parking lot

The experimental unit for the variable "color of a car entering a parking lot" would be the individual car. The color is being measured on each car entering the parking lot, making the car the experimental unit.

Most popular questions from this chapter

Parking on Campus Six vehicles are selected from the vehicles that are issued campus parking permits, and the following data are recorded: a. What are the experimental units? b. What are the variables being measured? What types of variables are they? c. Is this univariate, bivariate, or multivariate data?

1.11 Jeans A manufacturer of jeans has plants in California, Arizona, and Texas. A group of 25 pairs of jeans is randomly selected from the computerized database, and the state in which each is produced is recorded: \(\begin{array}{lllll}\text { CA } & \text { AZ } & \text { AZ } & \text { TX } & \text { CA } \\ \text { CA } & \text { CA } & \text { TX } & \text { TX } & \text { TX } \\ \text { AZ } & \text { AZ } & \text { CA } & \text { AZ } & \text { TX } \\ \text { CA } & \text { AZ } & \text { TX } & \text { TX } & \text { TX }\end{array}\) CA a. What is the experimental unit? b. What is the variable being measured? Is it qualitative or quantitative? c. Construct a pie chart to describe the data. d. Construct a bar chart to describe the data. e. What proportion of the jeans are made in Texas? f. What state produced the most jeans in the group? g. If you want to find out whether the three plants produced equal numbers of jeans, or whether one produced more jeans than the others, how can you use the charts from parts \(\mathrm{c}\) and \(\mathrm{d}\) to help you? What conclusions can you draw from these data?

Discrete or Continuous? Identify the following quantitative variables as discrete or continuous: a. Population in a particular area of the United States b. Weight of newspapers recovered for recycling on a single day c. Time to complete a sociology exam d. Number of consumers in a poll of 1000 who consider nutritional labeling on food products to be important

An Archeological Find An article in Archaeometry involved an analysis of 26 samples of Romano-British pottery, found at four different kiln sites in the United Kingdom. \({ }^{16}\) The samples were analyzed to determine their chemical composition, and the percentage of aluminum oxide in each of the 26 samples is shown in the following table. a. Construct a relative frequency histogram to describe the aluminum oxide content in the 26 pottery samples. b. What unusual feature do you see in this graph? Can you think of an explanation for this feature? c. Draw a dotplot for the data, using a letter (L, C, I, or A) to locate the data point on the horizontal scale. Does this help explain the unusual feature in part b?

Windy Cities Are some cities more windy than others? Does Chicago deserve to be nicknamed "The Windy City"? These data are the average wind speeds (in miles per hour) for 55 selected cities in the United States: \(^{5}\) a. Construct a relative frequency histogram for the data. (HINT: Choose the class boundaries without including the value \(x=35.1\) in the range of values.) b. The value \(x=35.1\) was recorded at \(\mathrm{Mt}\) t. Washington, New Hampshire. Does the geography of that city explain the observation? c. The average wind speed in Chicago is recorded as 10.3 miles per hour. Do you consider this unusually windy?
