Compare the Goodness of Fit Test and the Test for
Independence in terms of the number of variables and levels of
those that can be compared. In what ways are they similar or
different? (3 points)
Describe the following terms
a) stationary time series
b) seasonal time series
c) box test ( clearly define your notation and the null and
alternative hypotheses)
Identify which of the following statements will generate an
error. If there is an error, which phase of compiler construction
(if any) will be suitable to detect the following errors and
why?
1. A function is defined with the same signature as the previous
one.
2. A variable named ‘new’ is defined and initialized two times.
Once in main function and second in a “for” loop inside main
function.
3. A multi-line comment that starts but not ends.
4. The...
Activity 3: Which procedure?
For each question, determine which inference procedure is
appropriate (perform hypothesis test or construct a confidence
interval), and identify the parameter of interest (p, p1 – p2, µ,
µ1 – µ2, µd).

their freshman year?
Test or Interval Parameter

For the following test items, define one error and propose a
solution to the error.
1. Affective disorders such as paranoid delusions and mood
lability as well as the pathogenesis of anorexia nervosa may
surface in relation to or reaction to the puerperium, menopause, or
the postpartum period. Do you believe you could be at risk for any
of these disorders?
Problem:
Solution:
2.How often do you experience nightmares? 0-5 5-10 10-15 15-20
20 or more
Problem:
Solution:
True or False: When we apply the Box-Cox transformation to make the
best choice of the functional form for our model the first step of
analysis is to get the arithmetic mean of the sample
Y-values.
For this discussion, you will create an example to which the
chi-square test of independence could be applied. Develop a main
response in which you address the following:
Identify two categorical variables for which a chi-square test
of independence could be conducted.
Describe the categories of each.
Explain why these would be appropriate for this test.
Predict whether or not the chi-square test result would be
significant, and what this would imply about the variables.
Please answer all parts.
Part A. Which type of t-test is the procedure used to test
sample means from two independent samples? (multiple choice)
a. Paired-samples t-test
b. Homogeneity of variance
c. Related-samples t-test
d. Independent-samples t-test
Part B. Fill in blank
_________ is an assumption of the independent-samples t-test
that requires the populations represented by the 2 samples to have
equivalent variances.
Part C. If you wanted to determine how college students’
intelligence compared to the general population, and...
