Chapter 1: Problem 8

A relationship between two variables is described. In each case, we can think of one variable as helping to explain the other. Identify the explanatory variable and the response variable. Amount of fertilizer used and the yield of a crop

Short Answer

Expert verified
The explanatory variable is the 'Amount of fertilizer used' and the response variable is the 'Yield of a crop'.

Step by step solution

01

Identification of Explanatory Variable

The explanatory variable is the factor that is changed or controlled in an experiment. In this case, one can control the amount of fertilizer used on the crop. So, the explanatory variable would be the 'Amount of fertilizer used'.
02

Identification of Response Variable

The response variable is the factor that we measure or observe to see the effect of changes in the explanatory variable. Here, the changes in the crop production (yield) result from the amount of fertilizer used. Thus, the 'Yield of a crop' is the response variable.

Most popular questions from this chapter

State whether or not the sampling method described produces a random sample from the given population. The population is all trees in a forest. We walk through the forest and pick out trees that appear to be representative of all the trees in the forest.

Fast-Twitch Muscles and Race Example 1.5 studied a variant of the gene \(A C T N 3\) which inhibits fast-twitch muscles and seems to be less prevalent in sprinters. A separate study \(^{10}\) indicated ethnic differences: Approximately \(20 \%\) of a sample of Caucasians, approximately \(25 \%\) of a sample of Asians, and approximately \(1 \%\) of a sample of Africans had the gene variant. What are the variables in this study? Classify each as categorical or quantitative.

Do Parents Regret Having Children? In Data 1.4 on page \(24,\) we describe the results of a question asked by a national newspaper columnist: "If you had it to do over again, would you have children?" In addition to those results and a followup national survey, the Kansas City Star selected a random sample of parents from Kansas City and asked them the same question. In this sample, \(94 \%\) said "Yes." To what population can this statistic be generalized?

State whether or not the sampling method described produces a random sample from the given population. Send an email to a random sample of students at a university asking them to reply to the question: "Do you think this university should fund an ultimate frisbee team?" A small number of students reply. Use the replies to estimate the proportion of all students at the university who support this use of funds.

Describe an association between two variables. Give a confounding variable that may help to account for this association. People who own a yacht are more likely to buy a sports car.
