Chapter 1: Problem 9

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. Blood alcohol content (BAC) and number of alcoholic drinks consumed

Short Answer

Expert verified
The explanatory variable is 'Number of alcoholic drinks consumed' and the response variable is 'Blood Alcohol Content (BAC)'.

Step by step solution

01

Understand the Variables

In this context, the two variables are 'Blood Alcohol Content (BAC)' and 'Number of alcoholic drinks consumed'.
02

Identifying the Explanatory Variable

To identify the explanatory variable, ask the question - which variable can cause or determine the changes in the other? The number of alcoholic drinks consumed can affect the BAC, making it the explanatory variable.
03

Identifying the Response Variable

The response variable is the one that changes according to the explanatory variable. Since BAC changes based on the number of drinks consumed, BAC is the response variable.

Sampling Some Hardee's Restaurants The Hardee's Restaurant chain has about 1900 quickserve restaurants in 30 US states and 9 countries. \({ }^{28}\) Suppose that a member of the Hardee's administration wishes to visit six of these restaurants, randomly selected, to gather some first-hand data. Suppose the restaurants are numbered 1 to \(1900 .\) Use a randomnumber generator or table to select the numbers for 6 of the restaurants to be in the sample.

Hookahs are water pipes used for smoking flavored tobacco. One study \(^{12}\) of 3770 university students in North Carolina found that \(40 \%\) had smoked a hookah at least once, with many claiming that hookah smoke is safer than cigarette smoke. However, a second study observed people at a hookah bar and recorded the length of the session, the frequency of puffing, and the depth of inhalation. An average session lasted one hour and the smoke inhaled from an average session was equal to the smoke in more than 100 cigarettes. Finally, a third study measured the amount of tar, nicotine, and heavy metals in samples of hookah smoke, finding that the water in a hookah filters out only a very small percentage of these chemicals. Based on these studies and others, many states are introducing laws to ban or limit hookah bars. In each of the three studies, identify the individual cases, the variables, and whether each variable is quantitative or categorical.

State whether or not the sampling method described produces a random sample from the given population. Ask a random sample of people in a given school district "Excellent teachers are essential to the well-being of children in this community, and teachers truly deserve a salary raise this year. Do you agree?" Use the results to estimate the proportion of all people in the school district who support giving teachers a raise.

A biased sampling situation is described. In each case, give: (a) The sample (b) The population of interest (c) A population we can generalize to given the sample. 1.38 To investigate the growth of the canine population in New York City, 100 dogs are randomly selected from a registry of licensed pets in the city, and it is found that 78 of them have been neutered.

For the situation described: (a) What are the cases? (b) What is the variable and is it quantitative or categorical? Estimate the bending strength of beams by bending 10 beams until they break and recording the force at which the beams broke.
