Spilich et al. (1992) ran an experiment in which three groups of smokers participated in a driving simulation video game. The Active Smokers groups (AS) smoked immediately before the game but during it. The data follow, where the dependent variable is an adjusted score related to the number of collisions.

For studying the average pulse rates between three groups of
people: smokers, ex-smokers, and non-smokers, three independent
random samples of male subjects were selected from the three
populations. The data, sitting pulse rates per minute measured in
the morning, is listed below. Smokers: 88, 82, 80, 75 Ex-smokers:
70, 72, 73, 72 Non-smokers: 68, 70, 70, 75 Which of the followings

A study (B. Kristensen et al., J. Intern. Med. 232: 237–245
(1992)) considered the effect of prednisolone on severe
hypercalcaemia in women with metastatic breast can- cer. Of 30
patients, 15 were randomly selected to receive prednisolone and the
other 15 formed a control group. Normalization in their level of
serum-ionized calcium was achieved by 7 of the 15
prednisolone-treated patients and by 0 of the 15 patients in the
control group. Use Fisher’s exact test to find a P-value...

The article “HIV-positive Smokers Considering Quitting:
Differences by Race/Ethnicity” (E. Lloyd- Richardson, C. Stanton,
et al., Am J Health Behav, 2008:3–15) surveyed 444 HIV-positive
smokers. Of these, 281 were male and 163 were female. Consider this
to be a simple random sample. Can you conclude that more than 60%
of HIV-positive smokers are male?

7 and 8 go together
7. Two groups of subjects participated in an
experiment designed to test the effect of frustration on
aggression. The experimental group of 40 subjects
received a frustrating puzzle to solve, while the control group of
70 subjects received a very easy version of the same
puzzle. Levels of aggression was measured for both
groups where higher scores are indicative of higher levels of
aggression. The experimental group (high frustration)
had a mean aggression score of 4.0 and a standard...

(Gilson, et al., 2015) posited that establishing trust, which is
one of the major factors of project success in virtual teams, is
much more difficult to achieve. Concurrently, Katzenbach &
Smith, (2004) suggests that placing team members physically
together for roughly a week on project start-up will aid in
building trust and cohesiveness. So are we arguing that the
antidote to project failure due to impermanence of virtual teams is
to build trust?
