2. Mallory the mellitologist wanted to see whether the rate at which
bees die after exposure to Coumaphos, an insecticide, is dependent on
the age of the bees. In particular, she suspects that younger bees are at
higher risk of dying than older bees. This is problematic because when
younger bees die, the bee colony eventually collapses.
She collected a sample of 100 bees, recorded the time it took the bees
to die after exposure to Coumaphos (in years) and their age at death
(also in years).

Question 2 continued

If we assume a significance value of 5%, is the rate at which bees die
after exposure to Coumaphos, an insecticide, dependent on the age of
the bees?
a. The results are statistically significant because the p-value is less than 0.05.
b. The results are not statistically significant because the p-value is greater than
0.05.
c. The results are not statistically significant because the p-value is equal to
0.15314.
d. The results are statistically significant because the p-value is equal to 0.696.

3. What is the size of the effect and is the rate at which bees die after
exposure to an insecticide dependent on the age of the bees?
a. The effect size is 0.05, and the rate at which bees die after exposure
to an insecticide is not dependent on their age.
b. The effect size is 0.15314, and the rate at which bees die after
exposure to an insecticide is not dependent on their age.
c. The effect size is 0.696, and the rate at which bees die after
exposure to an insecticide is not dependent on their age.
d. The effect size is 0.15314, and the rate at which bees die after
exposure to an insecticide is dependent on their age.

4. Mallory hypothesizes that the rate at which bees die after exposure
to an insecticide is independent of the age of the bees. In which section
will she mention her hypothesis?
a. Results
b. Discussion
c. Abstract
d. Introduction

5. Mallory’s findings suggest that the rate at which bees die after
exposure to an insecticide is not dependent on their age. A group of
researchers doubted her failure to find a significant result. This would
reflect _____
a. Nonresponse bias
b. Type 2 error
c. Type 1 error
d. Self-selection bias

6. The study by Jenkins et al. (2017)
examined whether low-load (i.e., 30%
1RM) and high-load (i.e., 80% 1RM)
resistance training elicited different
responses in terms of muscle protein
synthesis and muscle hypertrophy/growth.
The following is a part of their results.
Imagine that you calculated Cohen's d for
muscle protein synthesis. Your calculations
reveal d = -0.14 and p value > 0.05 (0.97).
Which of the following is correct?
a. The effect size is negative, small and
significant
b. The effect size is negative, small and not
significant
c. The effect size is negative, medium and
significant
d. The effect size is negative, medium and not
significant

7. Which interpretation would be the best for the effect size that you
calculated?
a. Low-load (30% 1RM) and high-load (80% 1RM) resistance training did not
elicit different responses in terms of muscle protein synthesis
b. Low-load (30% 1RM) and high-load (80% 1RM) resistance training elicited
different responses in terms of muscle protein synthesis
c. High-load (80% 1RM) resistance training elicited more muscle protein
synthesis than low-load (30% 1RM)
d. Low-load (80% 1RM) resistance training elicited more muscle protein
synthesis than high-load (30% 1RM)

8. Imagine that you calculated Cohen's d for total repetitions. Your
calculations reveal d = -3.17 and p-value < 0.01. Which interpretation
would be the best for the effect size and p-value that you calculated?
a. Low-load (30% 1RM) and high-load (80% 1RM) training did not elicit different
responses in terms of muscle hypertrophy/growth
b. Low-load (30% 1RM) and high-load (80% 1RM) training did elicit different
responses in terms of muscle hypertrophy/growth
c. Not enough information is provided
d. I have no idea what you mean

9. What is the best interpretation of
the correlation between employment
and residence?
a. Employment and residence are
negatively correlated.
b. Employment causes owning a residence.
c. Residence ownership is strongly linked
with being employed.
d. Residence ownership is linked with
being employed, but the effect may be too
small to be meaningful.

10. Which of the following(s) is/are
correct? (Ignore the boxes. They are for
demonstration and irrelevant to the
question)
a. Credit cards and savings correlation is
medium (r = -0.48) and significant (P value <

b. Credit cards and debt correlation is medium
(r = 0.353) and insignificant (P value < 0.05,
0.056)
c. Two of the above
d. Neither of the above

significant
b. The correlation is positive, medium and
insignificant
c. The correlation is positive, small and significant

12. Parkinson’s Disease (PD) is a common neurodegenerative disorder. We
sought to synthesize studies on the prevalence of PD to obtain an overall
view of how the prevalence of this disease varies by age, by sex, and by
geographic location. We searched MEDLINE and EMBASE for epidemiological
studies of PD from 1985 to 2010. Data were analyzed by age group,
geographic location, and sex. Geographic location was stratified by the
following groups: 1) Asia, 2) Africa, 3) South America, and 4) Europe/North
America/Australia. Meta-regression was used to determine whether a
significant difference was present between groups. Forty-seven studies were
included in the analysis. Meta-analysis of the worldwide data showed a rising
prevalence of PD with age (all per 100,000): 41 in 40 to 49 years; 107 in 50 to
59 years; 173 in 55 to 64 years; 428 in 60 to 69 years; 425 in 65 to 74 years;
1087 in 70 to 79 years; and 1903 in older than age 80. It appears that this
article is _____
a. A media article published in the popular press
b. An empirical/primary journal article
c. A literature review
d. A meta-analysis

13. We examined the neuromuscular adaptations following 3 and 6
weeks of 80 vs. 30% one repetition maximum (1RM) resistance training
to failure in the leg extensors. Twenty-six men (age = 23.1 ± 4.7 years)
were randomly assigned to a high- (80% 1RM; n = 13) or low-load (30%
1RM; n = 13) resistance training group and completed leg extension
resistance training to failure 3 times per week for 6 weeks. It appears
that this article is _____
a. A media article published in the popular press
b. An empirical/primary journal article
c. A literature review
d. A meta-analysis
