Answer #1

**Answer:**

**1)** A researcher is interested in whether a
respondent’s raceplays a role in their confidence in the
police.

In this example,

**Independent Variable: confidence**

**Dependent Variable: raceplays**

**Because as confidence increases raceplays
increases.**

**2)** A researcher is interested in whether
respondents with an early age of first arrest have a higher
likelihood of gang membership.

In this example,

**Independent Variable: age of first arrest**

**Dependent Variable: gang membership**

**3)** A researcher is interested in whether a
neighborhood’s crime rate can be predicted by the strength of
social ties among its residents.

In this example,

**Independent Variable: strength of social
ties among its residents.**

**Dependent Variable: crime rate**

A researcher is interested in whether touch therapy
improves the weight gain of pre-term infants.
1. What is the independent variable? The independent
variable is the touch therapy being given.
2. What is the dependent variable? The dependent
variable is the weight of the pre-term infants.
3. What is the research hypothesis? The research
hypothesis is that the touch therapy increases the weight of the

4. What is the null hypothesis? The null hypothesis
is the touch therapy...

8.5 A researcher is interested in determining if an individuals
body fat percent- age can be predicted by the amount of weight the
individual can bench press. Suppose you have the following
data:
BPweight 190, 170, 200, 235, 265, 190, 220, 190
BodyFat 4.6, 5.4, 5.8, 5.9, 6.9, 7.2, 7.4, 7.6
(a) Create a scatterplot to determine if a linear relationship
exists between the explanatory variable and the response
variable.
(b) Calculate the least squares estimates and write the
equation....

Which situation most commonly leads to
convenience, availability, or accident
sampling?
When the researcher wants to maximize the likelihood that the
sample is representative of the population from which it is
selected.
When the researcher is knowledgeable about the study topic and
wants to make sure that the sample includes particular types of
members.
When the researcher is friendly with a few “informants” in the
hypothetical population who can help locate other members best
suited for the study, often those...

1. A dean of a business school is interested in determining
whether the mean grade point average (GPA) of students is less than
3.04. The population standard deviation is 0.41 A random sample of
200 students indicates a sample mean GPA of 2.94. A test is
conducted at the 0.05 level of significance to determine whether
the mean grade point average (GPA) of students is less than 3.04.
What are the most appropriate null and alternative hypotheses for
this test?...

Question 1) Which of the following are considered valid
criticisms of the legalistic model of crime and criminology?
a. Law in action departs substantially from the ideal behavior
of the law.
b. Focusing only on legally criminalized behavior makes it

ethnicity.
c. Legalistic definitions ignore acts that cause great harm.
d. The legalistic model suggests that these are absolute
standards for judging right and wrong.
e. All of the above....

BIOETHICS.
Bioethics as a field is relatively new, emerging only in the
late 1960s, though many of the questions it addresses are as old as
medicine itself. When Hippocrates wrote his now famous dictum
Primum non nocere (First, do no harm), he was grappling
with one of the core issues still facing human medicine, namely,
the role and duty of the...
