Question

**Using the statistical procedure THE WILCOXON SIGNED RANK
TEST**

that makes use of the magnitudes of the differences between measures and a

hypothesized location parameter rather than just the signs of the differences.

Sixteen laboratory animals were fed a special diet from birth through age 12 weeks. Their

weight gain (in grams) were as follows:

63 68 79 65 64 63 65 64 76 74 66 66 67 73 69 76

Can we conclude from these data that the diet results in a mean weight gain of less than 70

grams? Let α = 0.05.

Answer #1

Using the THE WILCOXON SIGNED-RANK TEST
Sixteen laboratory animals were fed a special diet from birth
through age 12 weeks. Their
weight gain (in grams) were as follows:
63 68 79 65 64 63 65 64 76 74 66 66 67 73 69 76
Can we conclude from these data that the diet results in a mean
weight gain of less than 70
grams? Let α = 0.05.
Note: There are two possible ways to analyze this data. Use the...

Kuya teaches a two-trimester course in Passionate Analysis
Involving Numbers (PAIN). He would like to know if these students
improved their scores in their second trimester of the course. Is
there a significant difference in PAIN scores? Apparently a couple
students were too 'pained' and dropped out after the first
trimester (too bad so sad).

Many standard statistical methods that you will study in Part II
of this book are intended for use with distributions that are
symmetric and have no outliers. These methods start with the mean
and standard deviation, x and s. For example,
standard methods would typically be used for the IQ and GPA data
here data215.dat.
(a) Find x and s for the IQ data. (Round your
answers to two decimal places.)

In what follows use any of the following tests/procedures:
Regression, multiple regressions, confidence intervals, one-sided
t-test or two-sided t-test. All the procedures should be done with
5% P-value or 95% confidence interval.
Upload the data HeartRate_Exercise. These data are based on 45
randomly chosen high school students.
SETUP: Is it reasonable to claim that students who
exercise more have lower heart beat rate at rest. Given the data
your job is to confirm or disprove this claim.
5. What test/procedure...

3. (Lesson 11) Use Minitab Express to conduct a
chi-square test to determine if there is a relationship between
gender and whether the student said that they would prefer to win
an Academy Award, Nobel Prize, or Olympic Medal. Use the
five-step hypothesis testing procedure. [25 points]
Step 1: State hypotheses and check
assumptions
Step 2:Compute the test
statistic
Step 3: Determine the
p-value
Step 4: Make a decision (reject or fail
to reject the null)
Step 5: State a real...

Your assignment is to do a detailed statistical analysis of the
data to be able to decide later what would be appropriate control
charts to monitor these variables.
The manager provides you data that the office has collected on
these two variables:
Time it takes since the patient checks-in until the patient
checks-out
Number of patients in the waiting room
Present a report to the manager with the results of the

You want to see if there is a statistical difference between the
two groups. Run descriptives and a two-tailed, two sample assuming
equal variance t-test.
